What is the shell called that interacts to form chemical bonds? What is the \"octet rule\"? T/F:
Ionic bonds are stronger than covalent bonds, because they don\'t dissociate easily. Which group
has stronger electro negativity\'s: Carbon & Hydrogen, or, Oxygen & Nitrogen T/F: A
condensation reaction is the addition of water, causing two monomers, for example, to combine
and become a larger polymer.
Solution
Ans. 1 Valence shell
The outermost shell of an atom is called valence shell. The electrons in outermost shell
participates in formation of chemical bond.
Ans. 2 Octet rule: “An atom gains or loses electron to attain the nearest inert gas configuration.”
Ans. 3. False.
Explanation 1: Not all Ionic bonds are stronger than every covalent bond. Some ionic bond are
weaker than specific covalent bond and vice-versa.
Explanation 2: Ionic bonds are stronger because of greater columbic attraction between
oppositely charged ions.
Ans. 4. Oxygen & Nitrogen has stronger electronegativity as they tend to attract electrons to
complete their octet with greater force than those Carbon & hydrogen.
Ans. 5. False.
Condensation reaction is the removal of water.
For example, when two amino acids join by peptide bond, there is loss of one water molecule.
As a result, the mass of product is LESSER than sum of the reactants..
