  • B
    $2\text{CH}_3\text{COOH}+\text{C}_2\text{H}_5\text{OH}\xrightarrow{\text{H}_2\text{SO}_4}\text{CH}_3\text{COOC}_2\text{H}_5+\text{H}_2\text{O}$
  • C
    $2 \mathrm{CH}_3 \mathrm{COOH}+2 \mathrm{Na} \rightarrow 2 \mathrm{CH}_3 \mathrm{COONa}+\mathrm{H}_2$
  • ✓
    $\mathrm{CH}_3 \mathrm{COOC}_2 \mathrm{H}_5+\mathrm{NaOH} \rightarrow \mathrm{CH}_3 \mathrm{COONa}+\mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}$
✓

Answer

Correct option: D.
$\mathrm{CH}_3 \mathrm{COOC}_2 \mathrm{H}_5+\mathrm{NaOH} \rightarrow \mathrm{CH}_3 \mathrm{COONa}+\mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}$
Saponification reaction is reaction of ester with base like $\ce{NaOH}$ to form the parent alcohol and sodium salt of carboxylic acid.
