Ethanol has higher boiling point than ethanol because

A

ethanol is a polar compound but ethanol is not

B

ethanol forms intermolecular hydrogen bond but ethanal does not

C

ethanol has higher molecular mass than ethanol

D

ethanol forms stronger intermolecular hydrogen bonds than does ethanol

Text Solution

Verified by Experts

The correct Answer is:
B
Both ethanol and ethanol are polar compounds and have comparable molecular masses . The high melting point of ethanol is mainly due to the presence of intermolecular hydrogen bonding between its molecules which is lacking in ethanol.
