In `HS^(-)`, `I^(-)`, `R-NH_(2)`, `NH_(3)` order of proton accepting tendency will be

A

`I_(-)gtNH_(3)gtRNH_(2)gtHS^(-)`

B

`NH_(3)gtRNH_(2)gtHS^(-)gtI_(-)`

C

`RNH_(2)gtNH_(3)gtHS^(-)gtI_(-)`

D

`HS^(-)gtRNH_(2)gtNH_(3)gtI_(-)`

Text Solution

Verified by Experts

The correct Answer is:
C
`RNH_(2)` is a stronger base than `NH_(3)`. Also `HI` is a strong acid and thus `I_(-)` is a weak base.
