`CH_(3)Br +Nu^(Theta) rarr CH_(3)-Nu +Br^(Theta)`
The decreasing order of the rate of the above reaction with nucleophiles `Nu^(Theta) A` to `D` is-
`[Nbar(u) =(A) phO^(-), (B) AcO^(-), (C)H bar(O),(D) CH_(3)bar(O)]`

A

`AgtBgtCgtD`

B

`BgtDgtCgtA`

C

`DgtCgtAgtB`

D

`DgtCgtBgtA`

Text Solution

Verified by Experts

The correct Answer is:
c
The stronger the acid , the weaker the conjugate base formed .
The acid character follows the order :
`CH_(3)COOHgtC_(6)H_(5)OHgtH_(2)OgtCH_(3)OH`
The basic character will follow the order
`CH_(3)COO^(-)ltC_(6)H_(5)O^(-)lt^(-)OHltCH_(3)O^(-)`
Hence , decreasing order of rate of given reactions with `Nu^(-)` is
`DgtCgtAgtB`
