Question

$H_{2}S{O}_4$ has higher viscosity than water. Reason being _____

• A. Intermolecular H-bonding
• B. Intramolecular H-bonding
• C. Covalent bonding
• D. Ionic nature of $H_{2}S{O}_4$

Answer 1

The correct option is A

Intermolecular H-bonding

For H-bonding, H should be attached to O, N or F. In case of $H_{2}S{O}_4$, totally 8 Hydrogen bonds can be formed in between the molecules.

This holds the molecules of $H_{2}S{O}_4$ tightly and doesn't allow to slide over each other.

This results in higher viscosity.
