(a) Catenation and tetravalency nature of carbon is the reason for the formation of a large number of compounds.
The property of formation of bonds with other carbon atoms to form long chains of different compounds is called catenation. Carbon has 4 electrons in its outermost orbit so it can either gain 4 electrons or lose 4 electrons to form a bond.
(b) (i) Carbon has 4 electrons in its outermost orbit so it can either gain 4 electrons or lose 4 electrons to form a bond but it is not possible hence it shares electrons with other atoms to form covalent bonds.
(ii) Since carbon form covalent bonds with other atoms and these bonds are weak so they can easily be breakable hence they have low melting and boiling points.
(c) (i) When sodium metal is added to ethanol hydrogen gas is released.
2Na + 2CH3CH2OH → 2CH3CH2ONa + H2
(ii) CH3COOH + NaOH → CH3COONa + H2O
