(a) a saturated hydrocarbon
(b) an unsaturated hydrocarbon with a double bond

Solution

(a) Saturated hydrocarbons are those compounds that have single bonds within their structure. For example alkanes like Methane( $C H_{4}$ ), Ethane( $C_{2} H_{6}$ ), Propane( $C_{3} H_{8}$ ), etc
The structures of Ethane( $C_{2} H_{6}$ ), Propane( $C_{3} H_{8}$ ) are as follows.
$\underset{E t h a n e}{C H_{3} - C H_{3}} \underset{P r o p a n e}{C H_{3} - C H_{2} - C H_{3}}$
(b) Unsaturated hydrocarbons are those compounds that have double or triple bonds. Unsaturated hydrocarbons with double bonds are alkenes like Ethene( $C_{2} H_{4}$ ), Propene( $C_{3} H_{6}$ ), Butene( $C_{4} H_{8}$ ).
The structures of Ethene( $C_{2} H_{4}$ ), Propene( $C_{3} H_{6}$ ), Butene( $C_{4} H_{8}$ ) is as follows.
$\underset{E t h e n e}{C H_{2} = C H_{2}}, \underset{P r o p e n e}{C H_{3} - C H = C H_{2}}, \underset{B u t e n e}{C H_{3} - C H_{2} - C H = C H_{2}}$
