Question

The functional group present in ${\mathrm{CH}}_3{\mathrm{COOC}}_2{\mathrm{H}}_5$ is-

• A. ketonic
• B. aldehydic
• C. ester
• D. carboxylic

Answer 1

The correct option is C

ester

A functional group is defined as a group of atoms that exist in a molecule and describes the characteristics reactions of organic compounds is called a functional group

The general formula of the ester is represented as ${\mathrm{RCOOR}}^{\text{'}}$.

In the given compound Ethyl acetate ${\mathrm{CH}}_3{\mathrm{COOC}}_2{\mathrm{H}}_5$ the functional group is $-\mathrm{COO}-$.

The functional group present in the given compound is the ester.

.So, the name of the compound is Ethyl acetate ${\mathrm{CH}}_3{\mathrm{COOC}}_2{\mathrm{H}}_5$.

The functional group in the ketonic compound is ${\mathrm{RCOR}}^{\text{'}}$.

The functional group in the aldehydic compound is $\mathrm{RCHO}$.

The functional group in the carboxylic acid compound is $\mathrm{RCOOH}$.

Hence, option (C) is the correct option.
