Questions asked by users might not always be phrased in the clearest way.
Butanoic acid has the highest boiling point among the given compounds. This is because butanoic acid has the strongest intermolecular forces (hydrogen bonding) compared to butane, butanol, and butanal. The stronger the intermolecular forces, the more energy is required to overcome them and vaporize the liquid, resulting in a higher boiling point.
