Which of the following has the highest nucleophilicity ?
`F^(-)`
`OH^(-)`
`CH_(3)^(-)`
`NH_(2)^(-)`

A

`F^(Ө)`

B

`overset (Ө) O H`

C

`overset (Ө) C H_3`

D

`overset (Ө) N H_2`

Text Solution

Verified by Experts

The correct Answer is:
C
Acidity : `HF gt H_2 O gt NH_3 gt CH_4`.
Basicity and nucleophilicity :
`F^(Ө) lt overset (Ө) O H lt overset (Ө) N H_2 lt overset (Ө) C H_3`
So `.^(Ө) CH_3` is the strongest nucleophile.
