The decreasing order of reactivity of m-...

The decreasing order of reactivity of `m-`nitrobromobenzene (I0, 2, 4, 6-trinitrobromo-benzene (II), `p-`nitrobromobenzene (III), and 2,4-dinitrobromobenzene (IV), towards `OH^(-)` ions is:

A

`I gt II gt III gt IV`

B

`II gt IV gt III gt I`

C

`IV gt II gt III gt I`

D

`II gt IV gt I gt III`

Text Solution

Verified by Experts

The correct Answer is:
B
More `-NO_(2)` group more will be reactivity towards `HO^(Θ)` ion towards `S_(N)Ar`.
