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

Text Solution

Verified by Experts

Ethers have less boiling points than th isomeric alcohols. For example, n-butyl alcohol `(C_(4)H_(9)OH)` boils at 390 K while dethyl ether `(C_(2)H_(5)-O-C_(2)H_(5))` has boiling point of 308 K . In alcohols, the molecules are linked by intermolecular hydrogen bonding which is absent in isomeric ethers.Consequently , alcohols boil at higher temerature.
