Which of the following is arranged in the increasing order of enthalpy of vaporization?

A

`NH_(3),PH_(3),AsH_(3)`

B

`AsH_(3),PH_(3),NH_(3)`

C

`NH_(3),AsH_(3),PH_(3)`

D

`PH_(3),AsH_(3),NH_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
Enthaply of vaporization is directly proportical to the strength of inter molecular force of attraction like hydrogen bonding vander Wall's force of attraction.
`NH rightarrow H- "bonding"`,
`PH_(3)andASH_(3)rightarrow "Vander walls bond"`.
