Which of the following is not a meta-directing group in electrophilic aromatic substitution?

A

`-SO_(3)H`

B

`-COOH`

C

`-CN`

D

`-NH_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
The groups `-SO_(3)H,-COOH`, and `-CN` are all moderately deactivating and meta directing howerver, group `-NH_(2)` is strongly activating and ortho-para directing.
