Question

Name the functional group present in the following compound.

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

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 number of atoms in the longest chain of the given compound is $6$, so hexane will be used.

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

In the given compound ${\mathrm{CH}}_3{\mathrm{COCH}}_2{\mathrm{CH}}_2{\mathrm{CH}}_2{\mathrm{CH}}_3$, the carbonyl is attached to the second carbon which indicates the presence of ketone in the compound. Therefore, the name of the compound is hexane-2-one.

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