Why benzoic acid has higher boiling point compared to naphthalene?

Benzoic acid has a higher boiling point than naphthalene primarily due to its ability to form hydrogen bonds, which are strong intermolecular forces. In contrast, naphthalene primarily exhibits weaker van der Waals forces. The presence of the carboxylic acid group in benzoic acid increases its polarity and intermolecular interactions, requiring more energy (higher temperature) to overcome these forces during boiling compared to naphthalene.
