Which of the following has the highest proton affinity ?

A

Stibine `(SbH_(3))`

B

Arsine `(AsH_(3))`

C

Phosphine `(PH_(3))`

D

Ammonia `(NH_(3))`

Text Solution

Verified by Experts

The correct Answer is:
D
`MH_(3)+H^(+) to MH_(4^(+))` As the size of the central atom increases, the stability of the conjugate acid decreases and hence the basic character decreases in the order. `NH_(3) gt PH_(3) gt AsH_(3) gt SbH_(3)`
