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_5`

Text Solution

Verified by Experts

The correct Answer is:
D
`NH_3` (in spite of lower molecular mass) has the highest enthalpy of vaporization on account of intermolecular H bonding. `PH_3` and `AsH_3` cannot exhibit intermolecular H bonding. Since the molecular mass of `PH_3` is lower, it has the lowest enthalpy of vaporization.
