Question

The functional groups present in the given compounds are:

A. Alcohol, ketone and ester
B. Ester and carboxylic acid
C. Carboxylic acid and ketone
D. Ester and alcohol

Answer 1

Hint: There are different types of the functional groups in organic chemistry. The functional groups of the organic compounds decide the chemical properties of the organic compounds in organic chemistry.

Complete step by step answer:
 - In the question it is asked to find the functional groups present in the given organic compound.
- There are various functional groups in organic chemistry like alkene, alcohol, aldehyde, ketone, ester, amine and etc.
- The structure of the given organic compound is as follows.

- The given compound contains R-COOH functional groups.
- R-COOH is called a carboxylic acid functional group.
- The given compound contains $ROCOC{{H}_{3}}$ functional group.
- $ROCOC{{H}_{3}}$ is called an ester functional group.

- Means the given compound contains two different functional groups (one carboxylic acid functional group and one ester functional group) in its structure.
- Therefore the two functional groups which are present in the given structure of the organic compound are carboxylic acid (R-COOH) and an ester functional group.

So the correct answer is “B”:
Additional Information:
Note: Ketone functional group is going to indicate with RCOR, Aldehyde is going to indicate with RCHO, alcohol functional group is going to indicate with R-OH and ester is going to indicate with RCOR. In organic chemistry every functional group has a separate name based on the presence of elements in the functional groups.
