At room temperature, HCl is a gas while HF is low boiling liquid. This is because

A

H - F bond is strong

B

H- F bond is weak

C

Molecules aggregate because of hydrogen bonding

D

HF is a weak acid

Text Solution

Verified by Experts

The correct Answer is:
C
HF forms inter-molecular hydrogen bonding so it exists as a low boiling liquid at room temperature. H - F bond is stroner than H - Cl but intramolecular forces will not affect the melting or boiling point (which depends on inter-molecular forces).
