Solution

The correct option is B ${C H}_{3} C O O H$
Among the given options, ${C H}_{3} C O O H$ is acetic acid, a carboxylic acid, so it will form a sweet-smelling ester, ${C H}_{3} {C O O C}_{2} H_{5}$ on reaction with ethanol.

The chemical reaction is given as

${C H}_{3} C O O H$ (aq) + ${C H}_{3} {C H}_{2} O H$ (aq) → ${C H}_{3} {C O O C}_{2} H_{5}$ (aq) + $H_{2} O$ (l)

So the correct answer is option a.
