Which of the following hydrogen halide is most volatile?

A

`HCL`

B

`HF`

C

`HI`

D

`HBr`

Text Solution

Verified by Experts

The correct Answer is:
B
`HF` has highest boiling point on account of intermolecular hydrogen bonding. But from `HCl` to `HI` the boiling point show a regular increase due to a corresponding increases in the magnitude of van der Waal's force of attraction as the size of the halogen increases.
