The nucleophilicities of CH(3)^(-) , NH(...

The nucleophilicities of `CH_(3)^(-) , NH_(2)^(-) , OH^(-) and F^(-)` decrease in which order ?

A

`CH_(3)^(-) gt NH_(2)^(-) gt OH^(-) gt F^(-)`

B

`OH^(-) gt NH_(2)^(-) gt CH_(3)^(-) gt F^(-)`

C

`NH_(2)^(-) gt OH^(-) gt CH_(3)^(-) gt F^(-)`

D

`CH_(3)^(-) gt OH^(-) gt F^(-) gt NH_(2)^(-)`

Text Solution

Verified by Experts

The correct Answer is:
A
In a period left to right E. N `uarr` ses and
Nucleophilicity `darr` ses .
So Nucleophilicity order =
`overset(Ө)(CH_(3)) gt overset(Ө)NH_(2) gt HO^(Ө) gt F^(Ө)`
