Why conc. `H_2 SO_4` is viscous and has high boiling point ?

Text Solution

Verified by Experts

There is extensive hydrogen bonding in conc. `H_2 SO_4` as shown below:

Extensive hydrogen bonding in conc. `H_2 SO_4`. Due to this hydrogen bonding the intermolecular forces are quite strong. Therefore, cond. `H_2 SO_4 ` is viscous and has high boiling point.
