Which of the following compounds has the highest boiling point?

Step-by-step solution

The boiling point of a compound depends on the strength of its intermolecular forces. CH ₃ CO ₂ H (acetic acid) has an - OH group and a C=O group, allowing it to form strong intermolecular hydrogen bonds. It exists as a dimer in the liquid phase, which significantly increases its boiling point. CH ₃ CH ₂ OH (ethanol) also exhibits intermolecular hydrogen bonding, but the extent and strength of hydrogen bonding are lesser than in acetic acid. CH ₃ COCH ₃ (acetone) has dipole-dipole interactions but lacks the ability
