Why do carboxylic acids generally have higher melting and boiling points than alcohols, ketones, and aldehydes of comparable mass?

The acid group is stabilized through resonance. The double bond can lie on either of the oxygens, and that stabilizes the molecule. More stable molecules have higher boiling points (and melting points). Alcohols, ketones, and aldehydes to not have resonance to stabilize them, so their boiling points are much lower.

because carboxylic acids have greater intensity of hydrogen bonding in them than the other groups
