The boiling point of carboxylic acids are very high compared to that alcohols with comparable molar masses why?
Pls answer ASAP

Dear student,

Carboxylic acids exhibit stronger intermolecular hydrogen bonding as compared to alcohols of comparable masses. The intermolecular hydrogen bonds of carboxylic acids do not break down easily giving them a higher boiling point. 

Carboxylic acids do have a higher boiling point than alcohols as alcohols have only 1 Oxygen and 1 hydrogen forming H-bonding While in case of Carboxylic acid 2 oxygen atoms are there which will form 2 H-bond simultaneously that will cause more interaction between the molecules that will require more heat for breaking those interactions.  The following figure shows the H-bonding (a) between carboxylic acid molecules and (b) among alcohol molecules.
