Question

Name the functional group present in the following compound.

${\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{CH}}_2\mathrm{COOH}$

Answer 1

Step 1:

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

Step 2:

The functional group present in the given compound is the carboxylic acid group as carbon atom is bonded to hydroxyl group bonded and oxygen by a double bond.

The carboxyl group is attached to the terminal carbon.

The given compound contains ${\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{CH}}_2\mathrm{COOH}$, four-carbon, the root word is “Buta” and the name of the compound is butanoic acid.

Hence, the functional group present in the following compound is a carboxylic acid.
