`CH_(3)Br+Nu^(-)rarrCH_(3)Nu+Br^(-)`
The decreasing order of the rate of the above reaction with nucleophiles `(Nu^(-))` A to D is :
`[Nu^(-)=(A)PhO^(-),(B)AcO^(-),(C)HO^(-),(D)CH_(3)O^(-)]`

A

D gt C gt A gt B

B

D gt C gt B gt A

C

A gt B gt C gt D

D

B gt D gt C gt A

Text Solution

Verified by Experts

The correct Answer is:
B
Phenoxide ion is less resonance stabilised than `AcO^(-)` Therefore, nucleophilicity decreases in the order `CH_(3)O^(-) (D) gt HO^(-) (C ) gt PhO^(-)(A) gt (CO^(-) (B)` Thus (B) is correct.
