Question

Boiling point of ether is lower compared to alcohol having same number of carbon atoms because:

• A. there are no intermolecular $H-$bonds
• B. there are no intramolecular $H-$bonds
• C. oxygen atom is attached to alkyl or aryl group
• D. none of the above

Answer 1

Answer: (A)

there are no intermolecular $H-$bonds

Solution:- (A) There are no intermolecular $H$-bonds

The boiling point of a substance depends on intermolecular forces. Alcohols have strong intermolecular Hydrogen bonds whereas ethers have weak dipole-dipole interactions, dispersion forces or Vander Wall forces depending upon the number of carbon atoms involved in alkyl group of ether. Thus due to the absence of intermolecular $H$-bonds in ethers, they have lower boiling points than alcohols.
