Organic chemistry
1) Organic chemistry is the study of carbon compounds and their properties. It is a separate discipline due to the vast number and variety of organic compounds, many of which are essential to life.
2) Carbon can form chains and rings by bonding to itself and other elements like hydrogen, oxygen, nitrogen and halogens. Functional groups like alcohols, aldehydes, ketones and carboxylic acids determine the properties and reactivity of organic molecules.
3) Chiral molecules are non-superimposable mirror images called enantiomers that can have different biological effects. The R/S system is used to distinguish these two forms.
The modern periodic table
The document discusses the structure and organization of the modern periodic table. Elements are arranged horizontally in order of increasing atomic number and grouped vertically into columns based on their electron configurations. The periodic table is divided into blocks including s-, p-, d- and f-blocks. An element's position in the table is determined by its atomic number and electron configuration, especially the outermost electrons.
Aromatic hydrocarbons
Benzene is an aromatic hydrocarbon with a planar hexagonal ring structure. Each carbon atom in the ring forms four bonds - one with a hydrogen atom and three sigma bonds with the other carbon atoms in the ring. The sixth valence electron of each carbon is delocalized and shared among all six carbon atoms, giving benzene unusual stability and properties compared to other unsaturated hydrocarbons. Aromatic compounds contain a benzene ring in their structure and include benzene itself along with methylbenzene and ethylbenzene. These aromatic hydrocarbons are liquids that are insoluble in water but soluble in non-polar solvents.
Essay question(structure atom)
1. The melting point is the temperature at which a solid turns to a liquid, and the boiling point is the temperature at which a liquid turns to a gas, both at a definite pressure.
2. Figure 2 shows the heating of substance X. It melts from a solid to a liquid at temperature Q, then boils from a liquid to a gas at temperature R. During these phase changes, the bonds between particles break as energy is absorbed to overcome attractive forces.
3. Figure 3 shows the electron configuration of element M with an electron valence of 1. Atom X and Y are isotopes with the same number of protons but different neutrons, and atom Y is radioactive and used for carbon pathway detection
C07 chemical bonding
The document discusses different types of chemical bonds and macromolecular structures. It explains that ionic bonds form between metals and non-metals via the transfer of electrons, giving ionic compounds high melting points and the ability to conduct electricity when molten or dissolved. Covalent bonds form between non-metals by the sharing of electrons, resulting in covalent compounds having low melting points and the inability to conduct electricity. Some covalent substances exist as macromolecules or giant molecular structures like diamond and graphite. These have very high melting points and different properties compared to simple molecules. Metallic bonding is also described, involving positive metal ions in a "sea of electrons" giving metals properties like malleability and high conductivity
CH.6 (PART II) - PROPERTIES of Ionic Compounds ppt. (2022).pptx
This document discusses the structure and properties of ionic compounds. It begins by explaining that ionic compounds are formed through the electrostatic attraction between oppositely charged ions. The ions form a crystalline lattice structure held together by strong ionic bonds. This lattice structure results in ionic compounds having high melting points, hardness, and brittleness. The document then discusses how ionic bonding occurs through the transfer of electrons between metals and nonmetals. It provides examples of writing chemical formulas and naming ionic compounds based on their ion charges.
Orbitals
An atomic orbital is defined as the region around the nucleus where an electron is most likely to be found. There are four quantum numbers that describe the orbitals: principal (n), angular momentum (l), magnetic (m), and spin (s). The principal quantum number indicates the electron shell and average distance from the nucleus. The angular momentum number determines the shape of the orbital. The magnetic number indicates the direction of the orbital. The spin number represents the electron's clockwise or counterclockwise spin. Common atomic orbitals include s, p, d, and f orbitals, which have different shapes and orientations determined by their quantum numbers.
Lewis dot structures
Lewis dot structures are a way to represent covalent bonding between atoms using dots to represent valence electrons. Atoms form bonds by sharing electrons in order to achieve stable electron configurations like the octet rule. Multiple bonds can form when more than one pair of electrons is shared between two atoms. Sometimes bonds form with both electrons coming from the same atom. Drawing accurate Lewis structures involves counting valence electrons and placing them between atoms to represent shared pairs and complete octets following the rules of covalent bonding. Resonance structures can occur when more than one valid Lewis structure exists for the same molecule.

Real-life applications of redox reactions include electrochemistry, combustion, photosynthesis, and industrial chemical production.
Relative atomic mass_&_mass_spectrometry[1][1]
This document provides information about relative atomic masses and how they are determined. It discusses how chemists use a relative scale rather than actual atomic masses, which are too small to measure. On this scale, carbon-12 is assigned a mass of 12. Isotopes of each element have different relative isotopic masses. A mass spectrometer is used to separate isotopes and determine their relative abundances. The average relative atomic mass (Ar) of an element is calculated based on the relative isotopic masses and abundances of its isotopes. Molecular and formula masses can also be determined by adding the relative atomic masses of each atom in a molecule or compound unit.

Matter
This document discusses matter and its properties. It defines the three common states of matter as solid, liquid, and gas. Solids have a definite shape and volume, with particles that are close together. Liquids take the shape of their container but have a definite volume, and their particles can move past one another. Gases spread out to fill their container and do not have a definite volume. The document also distinguishes between physical and chemical properties, and physical and chemical changes. Scientists use tools like balances and measuring cups to measure the mass and volume of matter.
Water is an example of matter
Water is an example of matter that is made of hydrogen and oxygen atoms. It has no smell, color, or taste and can change between solid, liquid, and gas states through melting, freezing, evaporating, and condensing. A pure substance consists of only one component while a mixture is made of two or more substances that can be either heterogeneous, where the parts can be seen separately, or homogeneous, where the parts cannot be seen individually. Waste comes in organic, recyclable, and non-recyclable forms.

5.6 Physical & Chemical Changes
Physical changes alter a substance's size, shape, or state but do not change its chemical composition. They can be reversed through processes like freezing, melting, evaporation, and condensation. Chemical changes form new substances with different properties that cannot be reversed, such as burning wood to form ash. The document discusses the differences between physical changes like freezing water and chemical changes like burning wood.
Solids liquids gases
Solids have strong molecular bonds that don't allow for much movement, so they can maintain their shape and size. Liquids have weaker bonds that allow for some movement, so they can flow and take the shape of their container. Gases have even weaker bonds and their molecules move freely, spreading to fill any open space unless contained in a sealed container. The document also discusses the reversible changes of melting, freezing, evaporation and condensation using water as an example.

The document describes the human digestive system. It discusses how digestion breaks down food mechanically and chemically. The digestive system includes the mouth, esophagus, stomach, small intestine, large intestine and anus. Accessory organs like the liver, gallbladder and pancreas also aid in digestion by producing enzymes and bile. Food is ingested, moved through the system, digested, absorbed and excreted in a multi-step process involving both mechanical and chemical breakdown.
Matter
This document discusses the properties and states of matter. It defines matter as anything that takes up space and has mass. Physical properties are characteristics that can be observed or measured without changing the substance, such as mass, volume, density, and state of matter (solid, liquid, gas). A mixture is a combination of two or more substances that keep their own properties, while a solution is a type of mixture where particles are evenly mixed but not easy to separate. The state that matter exists in depends on temperature and pressure - it can change states between solid, liquid and gas through physical processes like melting, freezing, boiling, evaporation and condensation that involve adding or removing heat.

Rutherford
Ernest Rutherford (1871-1937) was a notable British physicist and chemist who made seminal contributions to the development of the modern atomic model. Through his gold foil experiment in 1911, Rutherford was able to formulate the Rutherford model of the atom, which established that atoms have a small, positively charged nucleus surrounded by low-mass electrons. For this breakthrough discovery, Rutherford received numerous honors including the Nobel Prize in Chemistry in 1908. His work fundamentally changed scientific understanding of atomic structure.
Meinter
Lise Meitner was an Austrian/German physicist born in 1878 who made significant contributions to nuclear physics. She received her doctorate in 1905 as the second woman to earn a PhD from the University of Vienna. In 1938, Meitner, Otto Hahn, and Fritz Strassmann discovered nuclear fission when bombarding uranium with neutrons. This splitting of uranium atoms led to additional neutrons and the potential for an explosive chain reaction. Sadly, her discovery was later used in 1945 for the atomic bomb dropped on Hiroshima. Meitner received several honors for her work, including the Max Planck medal in 1949.
Gell mann
Murray Gell-Mann was born in 1929 and is still living. He graduated valedictorian from Columbia Grammar School and attended Yale University at age 15. Gell-Mann won the 1969 Nobel Prize in Physics. In 1964, he discovered the quark, which makes up protons and neutrons in the nucleus. Quarks have never been isolated due to their small size of 10-15 mm. Gell-Mann is also interested in activities like bird watching and collecting antiques.
Democritus
Democritus was a Greek philosopher born around 460-457 BC in Abdera, Thrace. He developed the first atomic theory, proposing that all matter is made up of indivisible atoms moving through empty space. Democritus believed that atoms were the fundamental building blocks of the natural world and that their behavior determined natural phenomena. He and his mentor Leucippus are considered the founders of atomic theory. Democritus was highly respected in his lifetime for making discoveries and predictions that were later proven true.
Chadwick
James Chadwick was a British physicist born in 1891 who is known for discovering the neutron. He received several honors for his work, including the Nobel Prize in Physics in 1935. Chadwick served in World War I and was a prisoner of war. He also participated in the Manhattan Project during World War II. Chadwick's model of the atom focused on neutrons, differing from Niels Bohr's model which depicted electrons in rings. Both models showed the structure of the atom but represented it differently.
