Solution

(a) The compound $C_{4} H_{9} - C O O - C_{2} H_{5}$ is a sweet-smelling ester.

(b) $C_{2} H_{5} - O H$ is the formula of ethanol which when treated with concentrated sulphuric acid at $170^{0} C$ to form an alkene called ethene. It has the molecular formula $C_{2} H_{4}$ .

(c) $C H_{4}$ (methane) is the compound which on repeated chlorination forms chloroform.

(d) $C H_{3} - O H$ (methanol or methyl alcohol) is added to alcohol to denature it.

(e) $C H_{3} - C O O H$ (ethanoic acid) is a constituent of vinegar.

(f) $C_{2} H_{5} - O H$ (ethanol) is the compound which is used to sterilise wounds and syringes.
