Ionic Compounds: Think of an ionic compound as a sea of ions. All these ions are carefully arranged in some sort of 3D pattern with positive and negative ions in specific locations in the pattern. Take common table salt, Sodium Chloride, as an example. In Sodium Chloride, there aren\'t specific NaCl molecules, but a mix of Na+ ions and Cl- ions. Each Na+ ion is surrounded by Cl- ions, and each Cl- ion is surrounded by Na+ ions. The whole structure is held together by the attraction between the positive and negative ions. Molecular Substances: A molecule is a group of atoms which are sharing electrons with one another through covalent bonds. Because the sharing results in a lower energy state, the atoms are more stable together than alone. When a sample of a molecular substance is looked at, say water (H2O), within the substance each molecule is being attracted to other molecules. These attractive forces are called intermolecular forces and they are much weaker than covalent bonds or ionic bonds. For a substance to melt and then boil, the forces which hold the substance together must be broken. When water boils, the intermolecular forces between H2O molecules are broken and the molecules separate from one another. (Note that the covalent bonds are NOT broken, the gas is still made up of H2O molecules, they\'re just not \"sticking\" to one another anymore.) As you can imagine, the ionic forces holding an ionic compound together are MUCH stronger than the intermolecular forces holding a molecular substance together. A lot more energy is required to break the ionic bonds. So, ionic substances melt at very high temperatures and boil at even higher temperatures.

Compounds, chem formulas & covalent bonds
Compounds are substances made of two or more elements that often have different properties than their constituent elements. Atoms bond together in compounds via chemical bonds formed by sharing valence electrons, called covalent bonds. A covalent bond forms when two atoms share one or more pairs of valence electrons, with single bonds sharing one pair and double or triple bonds sharing more pairs. The sharing of electrons leads to stable covalent compounds with properties like low melting and boiling points.
Chemistry of Life
The document provides an overview of chemistry concepts related to life, including atomic structure, molecules, compounds, chemical bonds, and organic chemistry. It discusses the building blocks of organic molecules like carbohydrates, lipids, proteins, and nucleic acids. Key points include that atoms bond to form molecules through ionic or covalent bonds, and that compounds have fixed ratios of elements that take on new properties.
bonding_regents_chem.ppt
This document defines chemical bonding and describes the three main types of bonds: metallic, ionic, and covalent. Metallic bonds form a crystalline lattice structure with freely moving electrons. Ionic bonds form when ions with opposite charges are attracted to each other via electrostatic forces. Covalent bonds form when atoms share electrons to achieve stable electron configurations. The type of bonding determines various physical properties like melting point, hardness, and conductivity.
Properties of covalent substances, metals and ionic compounds
This document discusses the properties of three classes of substances: molecular substances, ionic compounds, and metallic solids. Molecular substances exist as gases, liquids, or solids depending on the strength of intermolecular forces between molecules. Ionic compounds form crystalline structures with positive and negative ions in repeating patterns, making them hard and brittle solids with high melting points. Metallic solids consist of layers of metal atoms that share delocalized valence electrons, giving metals properties like conductivity and malleability.

InterMolecular forces lesson ppt physical science
This document discusses intermolecular and intramolecular forces. It defines intermolecular forces as the attractive forces between molecules, including London dispersion, dipole-dipole, hydrogen bonding, and ion-dipole forces. Intramolecular forces are the stronger chemical bonds within molecules. The effects of intermolecular forces on properties like boiling point, surface tension, vapor pressure, and viscosity are explained. Stronger intermolecular forces result in higher boiling points, surface tension, and viscosity as well as lower vapor pressure.
NaCl Its the coulombic interaction between Na.pdf
NaCl : It\'s the coulombic interaction between Na+ and Cl- due to which crystal
exists. It\'s not ionic intereaction. It\'s ionic interaction. (very strong). NaCl dissolves in water.
It\'s not due to hydrogen bonding. It\'s due to strong ion-dipole interactions. Initially, the
positive and negative ion are only attracted to each other. The water molecules are hydrogen
bonded to each other. If the crystal is to dissolve, these bonds must be broken. Negative chloride
ions on the surface are attracted by neighboring positive sodium ions and by the partially positive
hydrogen atom in the polar water molecule (See the graphic on the left). Similarly, the positive
sodium ions are attracted by both chloride ions and the partially negative oxygen atom in the
polar water molecule. A \"tug-of-war\" occurs for the positive and negative ions between the
other ions in the crystal and the water molecules. Several water molecules are attracted to each of
the ions. Whether the crystal dissolves is determined by which attractive force is stronger. If the
internal ionic forces in the crystal are the strongest, the crystal does not dissolve. This is the
situation in reactions where precipitates form. If the attractions for the ions by the polar water
molecules are the strongest, the crystal will dissolve. This is the situation in sodium chloride.
Once the ions are released from the crystals, the ions are completely surrounded by water
molecules. Note that the proper atom in the water molecule must \"point\" toward the correct ion.
The charge principle and the partial charges in the polar molecule determine the correct
orientation. Partially negative oxygen atoms in the water molecule interact with the positive
sodium ion. Partially positive hydrogen atoms in the water molecule interact with the negative
chloride ion. Sugar : The interaction between sugar molecule and water is greater than between
sugar molecules. So When sugar is put into water, it likes to form hydrogen bonds with water. So
it breaks glycosidic linkages and forms hydrogen bonds with water. Initially it separates into
polymer sugar chains, but later it dissociates into individual molecules.

Kinetic molecular theory explains the states of matter based on the idea that matter is composed of tiny particles in constant motion. It describes the differences between solids, liquids, and gases in terms of intermolecular forces and molecular motion. In liquids, molecules are close together and can move past one another, allowing liquids to flow. Solids have molecules held rigidly in position with little motion. The properties of liquids, such as viscosity, surface tension, vapor pressure, and boiling point, depend on the balance between kinetic energy and intermolecular forces between molecules.

Intermolecular Forces
Intramolecular forces hold atoms together within a molecule, such as covalent bonds. Intermolecular forces exist between separate molecules and include dipole-dipole interactions between polar molecules, hydrogen bonding, ion-dipole interactions, and dispersion forces between all molecules due to induced dipoles. The type of intermolecular force present influences physical properties like melting and boiling points, with ionic compounds having the highest melting points due to strong ion-ion interactions.
Lecture 8.4c- Intermolecular Forces
1) Ammonia (NH3) is a polar molecule that has tetrahedral shape due to hydrogen bonding between nitrogen and hydrogen atoms.
2) Intermolecular forces include dipole-dipole interactions between polar molecules and London dispersion forces between all molecules.
3) Hydrogen bonding is a strong type of dipole-dipole interaction that occurs between molecules containing hydrogen bonded to nitrogen, oxygen, or fluorine.
Chapters 2&3
This document provides a summary of basic chemistry concepts covered in chapters 2 and 3 of a unit 1 notes document. It discusses the following key points in 3 sentences:
Matter is anything that takes up space and has specific physical and chemical properties. Atoms are the basic building blocks of matter and consist of a nucleus with protons and neutrons surrounded by electrons. Compounds are formed when two or more elements chemically combine, resulting in new substances with different properties than the individual elements.
Bonding and Structure
The document discusses different types of bonding: ionic, covalent, and metallic. Ionic bonding involves the transfer of electrons between metals and non-metals to form ions. Covalent bonding involves the sharing of electron pairs between non-metals. Metallic bonding involves a sea of delocalized electrons that are attracted to cationic metal ions arranged in a lattice. Each type of bonding results in different material properties depending on whether electrons are transferred, shared, or free to move.
2012 topic 4.3 intermolecular forces and physical properties
Intermolecular forces describe the attractions between particles in compounds and depend on the structure. Strong ionic, metallic and covalent bonds in complex structures result in high melting points and conductivity. Weaker van der Waals forces between simple molecules affect properties like boiling points, with polar molecules having higher points due to dipole interactions and hydrogen bonding.
Ionic bonds and Ionic compounds
This document describes the formation and properties of ionic compounds. Ionic bonds form when oppositely charged ions attract each other to form electrically neutral compounds. Ionic compounds have high melting and boiling points because the ionic bonds between ions require a large amount of energy to overcome. The ions are tightly packed in a crystal lattice structure. Physical properties like conductivity depend on whether the ions are free to move or locked in place. Smaller or more highly charged ions result in stronger ionic bonds and higher lattice energies.
Chemistry of life
All matter is composed of atoms that are made up of protons, neutrons, and electrons. Atoms can bond together to form molecules or ionic compounds. There are two main types of bonds between atoms - ionic bonds which form when atoms transfer electrons, and covalent bonds which form when atoms share electrons. Compounds have distinct properties compared to the individual elements. Water is a universal solvent that is able to dissolve many ionic compounds due to its polar nature. The pH scale measures the concentration of hydrogen ions in solutions and indicates whether they are acidic, basic, or neutral.
Lesson 2 Intermolecular Forces.pptx
This document defines and differentiates the main types of intermolecular forces: dipole-dipole forces, London dispersion forces, ion-dipole forces, and hydrogen bonding. It provides examples of polar and nonpolar molecules, and describes the characteristics of each type of intermolecular force, including their relative strengths and the molecules between which they typically occur.

The document discusses the properties of solids and liquids based on the kinetic molecular theory. It explains that solids have a defined structure with particles held closely together by strong intermolecular forces, while liquids lack a defined structure but their properties can be qualitatively understood by considering the intermolecular forces between their particles. The document then discusses several properties of liquids including surface tension, viscosity, vapor pressure, boiling point, and heat of vaporization, relating them to the intermolecular forces between the liquid particles.

Intermolecular Forces
Intramolecular forces hold atoms together within a molecule, such as covalent bonds. Intermolecular forces exist between separate molecules and include dipole-dipole interactions between polar molecules, hydrogen bonding, ion-dipole interactions, and dispersion forces between all molecules due to induced dipoles. The type of intermolecular force present influences physical properties like melting and boiling points, with ionic compounds having the highest melting points due to strong ion-ion interactions.
Lecture 8.4c- Intermolecular Forces
1) Ammonia (NH3) is a polar molecule that has tetrahedral shape due to hydrogen bonding between nitrogen and hydrogen atoms.
2) Intermolecular forces include dipole-dipole interactions between polar molecules and London dispersion forces between all molecules.
3) Hydrogen bonding is a strong type of dipole-dipole interaction that occurs between molecules containing hydrogen bonded to nitrogen, oxygen, or fluorine.
Chapters 2&3
This document provides a summary of basic chemistry concepts covered in chapters 2 and 3 of a unit 1 notes document. It discusses the following key points in 3 sentences:
Matter is anything that takes up space and has specific physical and chemical properties. Atoms are the basic building blocks of matter and consist of a nucleus with protons and neutrons surrounded by electrons. Compounds are formed when two or more elements chemically combine, resulting in new substances with different properties than the individual elements.
Bonding and Structure
The document discusses different types of bonding: ionic, covalent, and metallic. Ionic bonding involves the transfer of electrons between metals and non-metals to form ions. Covalent bonding involves the sharing of electron pairs between non-metals. Metallic bonding involves a sea of delocalized electrons that are attracted to cationic metal ions arranged in a lattice. Each type of bonding results in different material properties depending on whether electrons are transferred, shared, or free to move.
2012 topic 4.3 intermolecular forces and physical properties
Intermolecular forces describe the attractions between particles in compounds and depend on the structure. Strong ionic, metallic and covalent bonds in complex structures result in high melting points and conductivity. Weaker van der Waals forces between simple molecules affect properties like boiling points, with polar molecules having higher points due to dipole interactions and hydrogen bonding.
Ionic bonds and Ionic compounds
This document describes the formation and properties of ionic compounds. Ionic bonds form when oppositely charged ions attract each other to form electrically neutral compounds. Ionic compounds have high melting and boiling points because the ionic bonds between ions require a large amount of energy to overcome. The ions are tightly packed in a crystal lattice structure. Physical properties like conductivity depend on whether the ions are free to move or locked in place. Smaller or more highly charged ions result in stronger ionic bonds and higher lattice energies.
Chemistry of life
All matter is composed of atoms that are made up of protons, neutrons, and electrons. Atoms can bond together to form molecules or ionic compounds. There are two main types of bonds between atoms - ionic bonds which form when atoms transfer electrons, and covalent bonds which form when atoms share electrons. Compounds have distinct properties compared to the individual elements. Water is a universal solvent that is able to dissolve many ionic compounds due to its polar nature. The pH scale measures the concentration of hydrogen ions in solutions and indicates whether they are acidic, basic, or neutral.
Lesson 2 Intermolecular Forces.pptx
This document defines and differentiates the main types of intermolecular forces: dipole-dipole forces, London dispersion forces, ion-dipole forces, and hydrogen bonding. It provides examples of polar and nonpolar molecules, and describes the characteristics of each type of intermolecular force, including their relative strengths and the molecules between which they typically occur.

Uncouple agents will never disrupt the electron transport (they will.pdf
Uncouple agents will never disrupt the electron transport (they will not damage or disrupt the
mitochondrial structure), they only inhibit the ATP synthesis and best example for this Uncouple
agents are 2,4-dinitrophenol (DNP) and carbonylcyanide-ptrifluoromethoxyphenylhydrazone
(FCCP) and these agents are known to bear H+ and are capable of diffusing into the matrix. Like
this these two chemicals successfully reduce the electrochemical potential across the inner
mitochondrial membrane and as a result you can see an inhibition of ATP synthesis.
2,4-Dinitrophenol, dicumarol and carbonyl cyanidep-trifluorocarbonyl-cyanide methoxyphenyl
hydrazone (FCCP) chemicals have hydrophobic character, thus these are easily soluble in the
bilipid membrane (this gives them any easy entry into the matrix in its protonated form and thus
they releases a proton and can successfully dissipate the proton gradients. Another things through
resonance stabilization will delocalize the charge which is there on anionic forms and thus this
chemical again will diffuse back across the membrane will try to pick up a proton and will try to
repeat the process) and in these chemical decouples by having the dissociable protons will carry
protons from the intermembrane space to the matrix, so that the pH gradient existing there can be
collapsed and all the potential energy of the proton gradient will be seen losing as mere heat.
Research has showed when 2,4-dintrophenol is added to the reaction mixture, it has uncoupled
electron transfer from that of ATP synthesis and as a result the oxygen is completely seen to be
consumed in the absence of ADP.

Quicksort AlgorithmQuicksort is a divide and conquer algorithm. Q.pdf
Quicksort Algorithm:
Quicksort is a divide and conquer algorithm. Quicksort first divides a large array into two
smaller sub-arrays: the low elements and the high elements. Quicksort can then recursively sort
the sub-arrays.
The steps are:
The base case of the recursion is arrays of size zero or one, which never need to be sorted.
The pivot selection and partitioning steps can be done in several different ways; the choice of
specific implementation schemes greatly affects the algorithm\'s performance.
This algorithm is based on Divide and Conquer paradigm. It is implemented using merge sort. In
this approach the time complexity will be O(n log(n)) . Actually in divide step we divide the
problem in two parts. And then two parts are solved recursively. The key concept is two count
the number of inversion in merge procedure. In merge procedure we pass two sub-list. The
element is sorted and inversion is found as follows
a)Divide : Divide the array in two parts a[0] to a[n/2] and a[n/2+1] to a[n].
b)Conquer : Conquer the sub-problem by solving them recursively.
1) Set count=0,0,i=left,j=mid. C is the sorted list.
2) Traverse list1 and list2 until mid element or right element is encountered .
3) Compare list1[i] and list[j].
i) If list1[i]<=list2[j]
c[k++]=list1[i++]
else
c[k++]=list2[j++]
count = count + mid-i;
4) add rest elements of list1 and list2 in c.
5) copy sorted list c back to original list.
6) return count.
void quickSort(int arr[], int left, int right) {
int i = left, j = right;
int tmp;
int pivot = arr[(left + right) / 2];

John is suffering from fifth disease.
It is caused by an airborne virus called parvovirus B19. It causes a red rash on children\'s arms,
legs and cheeks and hence it is also known as \"slapped cheek disease\". It is more common in
children, but it can be more severe for pregnant women or anyone with a compromised immune
system. For children with healthy immune systems, fifth disease is a common, mild illness that
rarely presents lasting consequences.
John can go to kindergarden- in the initial stages of this disease the symptoms such as headache,
sore throat, running nose etc are seen, most young people develop a red rash that frist appears on
cheeks, the rash often spreads to the arms, legs and trunk of the body within a few days. The rash
may last for weeks, but usually by the time you see it you\'re no longer contagious.
This infection is common among school age children but is rare in infants and adults
Measles
A paramyxovirus causes the disease, it usually begins with nasal congestion, eye redness,
swelling and tearing, cough, lethargy and high fever. On the third or fourth day of the illness, the
child will develop a red rash on the face, which dpreads rapidly and lasts about 7 days. A
measles rash, which appears as red, itchy bumps, commonly develops on the head and slowly
spreads to other parts of the body.

Ionic Compounds Think of an ionic compound as a .pdf
- 1. Ionic Compounds: Think of an ionic compound as a sea of ions. All these ions are carefully arranged in some sort of 3D pattern with positive and negative ions in specific locations in the pattern. Take common table salt, Sodium Chloride, as an example. In Sodium Chloride, there aren't specific NaCl molecules, but a mix of Na+ ions and Cl- ions. Each Na+ ion is surrounded by Cl- ions, and each Cl- ion is surrounded by Na+ ions. The whole structure is held together by the attraction between the positive and negative ions. Molecular Substances: A molecule is a group of atoms which are sharing electrons with one another through covalent bonds. Because the sharing results in a lower energy state, the atoms are more stable together than alone. When a sample of a molecular substance is looked at, say water (H2O), within the substance each molecule is being attracted to other molecules. These attractive forces are called intermolecular forces and they are much weaker than covalent bonds or ionic bonds. For a substance to melt and then boil, the forces which hold the substance together must be broken. When water boils, the intermolecular forces between H2O molecules are broken and the molecules separate from one another. (Note that the covalent bonds are NOT broken, the gas is still made up of H2O molecules, they're just not "sticking" to one another anymore.) As you can imagine, the ionic forces holding an ionic compound together are MUCH stronger than the intermolecular forces holding a molecular substance together. A lot more energy is required to break the ionic bonds. So, ionic substances melt at very high temperatures and boil at even higher temperatures.
