Question

What type of intermolecular bonding occurs in gaseous CH$_4$?

• A. Covalent
• B. Ionic
• C. Hydrogen
• D. Van der Waals’

Hint:

Non-polar molecules like CH$_4$ exhibit only weak Van der Waals' forces (London dispersion) in the gaseous state.

Answer 1

The Correct Option is D

CH$_4$ (methane) is a non-polar molecule. In its gaseous state, the intermolecular forces between CH$_4$ molecules are weak London dispersion forces, which are a type of Van der Waals’ force. There is no hydrogen bonding, covalent bonding between molecules, or ionic interaction.
