The stability of the hydrides follows the order

A

`NH_(3) gt PH_(3) gt AsH_(3) gt SbH_(3)`

B

`NH_(3) lt PH_(3) lt SbH_(3) gt AsH_(3)`

C

`PH_(3) gt NH_(3) gt AsH_(3) gt SbH_(3)`

D

`AsH_(3) gt NH_(3) gt PH_(3) gt SbH_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A
Thermal stability of hydrides of group 15 decreases down the group. Thus it is the order:
`NH_(3) gt PH_(3) gt AsH_(3) gt SnH_(3)`
