Which of the following compound has the highest boiling point

A

`HCl`

B

`HBr`

C

`H_2SO_4`

D

`HNO_3`

Text Solution

Verified by Experts

The correct Answer is:
C
Due to high electronegative O atom in `H_2SO_4` and `HNO_3`, they show intermolecular hydrogen bonding. The difference in electronegativities of `N(3.0) and O(3.5)` is only 0.5 but that of between `S(2.5)` and O is 1. So O is more negatively charged in `H_2SO_4` due to which `H_2SO_4` will form stronger inter molecular hydrogen bonding than `HNO_3`. So `H_2SO_4` has hgihest boiling point.
