Question

${\text{CH}}_3\text{COOH}\left(\mathrm{aq}\right)+{\text{CH}}_3{\text{CH}}_2\text{OH}\left(\mathrm{aq}\right)\underset{}{\overset{\text{Acid catalyst}}{\to }}$ ${\text{+ H}}_2\text{O}\left(\mathrm{aq}\right)$
This reaction is called .

• A. saponification
• B. esterification
• C. $C{H}_{3}COOC{H}_3$
• D. $C{H}_{3}COOC{H}_{2}C{H}_3$

Answer 1

Answer: (B), (D)

The correct options are
B esterification
D $C{H}_{3}COOC{H}_{2}C{H}_3$

$\bullet$ Esters are formed by the reaction between a carboxylic acid and an alcohol in the presence of a mineral acid catalyst.

$\bullet$ In the given reaction, ethanoic acid $\left(C{H}_{3}COOH\right)$ is reacting with ethanol $\left(C{H}_{3}C{H}_{2}OH\right)$ in the presence sulphuric acid to give an ester, ethyl ethanoate $\left(C{H}_{3}COOC{H}_{2}C{H}_3\right)$. Hence, this is an esterification reaction.
