Butanoic acid boils at about 164 °C and butan-1-ol at about 118 °C. Both can form a hydrogen bond. Which reason best explains why the carboxylic acid has the higher boiling point?

A.The acid has both O–H and C=O, so it hydrogen bonds more stronglyB.The acid ionizes fully in the pure liquid, so its ions attractC.The acid has a C=O but no O–H, so only dipoles attractD.The alcohol has a smaller molar mass, so it boils lower
