    True
  • The hydroxyl group in alcohols makes them acidic
    True
  • Alcohols are weakly acidic due to the presence of the hydroxyl group

    True
  • Carboxylic acids have higher boiling points than alcohols due to stronger intermolecular hydrogen bonding.
  • The boiling point of carboxylic acids is higher than that of corresponding alcohols.
  • Formic acid is used as a preservative and a disinfectant.
