Question

Why alcohols and ethers of comparable molecular mass have different boiling points?

Answer 1

Answer:

Alcohols undergo intermolecular H-bonding and hence exist as associated molecules. Since lesser energy is required to break weak dipole-dipole attractions than to break H-bonds in associated molecules of alcohols, therefore, boiling points of alcohols are much higher than ethers of comparable molecular mass.
