Identify correct order of reactivity in electronphilic substitution reactions of the following compounds

A

`1gt2gt3gt4`

B

`4gt3gt2gt1`

C

`2gt1gt3gt4`

D

`2gt3gt1gt4`

Text Solution

Verified by Experts

The correct Answer is:
C
We know, during electrophilic substitution of arenes electron donating groups activates the ring · (and are o, p-directing) and electron withdrawing groups deactivates the ring (and are m-directing). Halogens are o, p-directing but are not much activating. Therefore, correct order is `2gt3gt1gt4`
