Question

Functional group present in carboxylic acid is

• A. -CHO
• B. -COOH
• C. -CO-
• D. - COOR

Answer 1

The Correct Option is B

To solve the problem, we need to identify the correct functional group that characterizes a carboxylic acid.

1. Understanding Functional Groups:
–CHO is the aldehyde group.
–COOH is the carboxylic acid group.
–CO– represents the ketone group (carbonyl group within a chain).
–COOR is the ester group.

2. Functional Group of Carboxylic Acid:
Carboxylic acids are defined by the presence of the –COOH group, which consists of both a carbonyl (C=O) and a hydroxyl (–OH) group attached to the same carbon atom.

Final Answer:
The functional group present in carboxylic acid is $ \text{–COOH} $
