Vedclass · Accepted Answer

Formation of intermolecular hydrogen bonding

Vedclass · Answer

(D) $1$. Carboxylic acids $(R-COOH)$ exhibit higher boiling points than alcohols, aldehydes, ketones, and alkanes of comparable molecular masses.$2$. This is due to the presence of extensive intermolecular hydrogen bonding between the carboxylic acid molecules.$3$. In the vapor phase, carboxylic acids often exist as stable dimers held together by two intermolecular hydrogen bonds.$4$. This strong association requires more energy to break, resulting in a higher boiling point.

Identify the reason for the highest boiling point of $R-COOH$ as compared to alkanes, ethers, alcohols and aldehydes.
