A

`I gt II gt III`

B

`II gt III gt I`

C

`III gt II gt I`

D

`II gt I gt III`

Text Solution

Verified by Experts

The correct Answer is:
B
Key idea Order of strengths of the given carboxylic acids can be determined by the concept of I-effect.
The oxygen atom present in the ring shows I-effect. As the distance between oxygen and -COOH group increases, -I effect of oxygen decreases.
Thus, corresponding carboxylic acid will show less acidic nature.
The correct order of strengths of the carboxylic acids is
