Rank the following in order of decreasing rate of reation with alkoxide ion `(CH_(3) CH_(2) O^(-))` in a nucleophilic aromatic substitution reaction :
(1)

A

`3 gt 4 gt 1 gt 2`

B

`3 gt 4 gt 2 gt 1`

C

`2 gt 1 gt 4 gt 3`

D

`4 gt 3 gt 2 gt 1`

Text Solution

Verified by Experts

The correct Answer is:
A
`{:(,3,gt,4,gt,1,gt,2,),(NO_(2) rarr,-M,,-M,,-M,,-I,),(NO_(2) rarr,-M,,-I,,,,,):}`
`NO_(2)` is ortho-para director for nucleophilic aromatic substitution.
