Amost `NH_(2) , PH_(3),AsH_(3)` and `SbH_(3)` the one with highest bolding point is

A

`NH_(2)` because of lower molcular weight

B

`SbH_(3)` because of higher molcular weight

C

`PH_(2)` because of H- bonding

D

`AsH_(3)` because of lower molcular weight

Text Solution

Verified by Experts

The correct Answer is:
b
As molcular weight increasing increases magnitude of van der waal's force of arraction increases
Therefore,boling point increases .Through `NH_(3)` has strong H- bonding point of `SbH_(3)` hihhest that to highest molecular weight point `NH_(3) = 238.5 K and SbH_(3) = 254.6 K`
