MCQ
Acetic acid exists as dimer in benzene due to
  • A
    Condensation reaction
  • Hydrogen bonding
  • C
    Presence of carboxyl group
  • D
    Presence of hydrogen atom at $\alpha - $ carbon

Answer

Correct option: B.
Hydrogen bonding
b
Benzene is a non-polar solvent and acetic acid is a polar molecule. In benzene, two molecules of acetic acid form intermolecular $H$-bond and hence it exists as a dimer in Benzene.
