Answers
a) Saturated hydrocarbons: Hydrocarbons in which the carbon atoms are linked to each other by single bonds only are known as saturated hydrocarbons.
Examples include ethane (CH
3
−CH
3
), butane CH

−CH
2
−CH

−CH
3
etc.
(b) Unsaturated hydrocarbons: Hydrocarbons in which the carbon atoms are linked to each other by double (C=C) or triple (C≡C) bonds are known as unsaturated hydrocarbons.
Examples include ethene (H
2
C=CH
2
), propyne (HC≡CH−CH
3
etc.
(c) (1) Catenation is the linkage of atoms of the same element into longer chains.
(2) Catenation mostly occurs in carbon, which forms a covalent bond with other carbon atoms to form longer chains and structures.
(3) Some other elements also show catenation e.g., silicon, sulphur and Boron.
Examples include the following:
(a) CH

(Ethane)
(b) CH
