A. Carboxylic acids have the general formula R-COOH.
B. The carboxyl group is nonpolar.
C. Carboxylic acids are named with the suffix -oic acid.
D. The carbon adjacent to the carboxyl group is called the alpha carbon.

Question 21 (0.5 points)
Why do carboxylic acids have high boiling points and melting points?

A. They are polar molecules.
B. They exhibit two intermolecular hydrogen bonds.



Answer :

Final answer:

Carboxylic acids have high boiling points and melting points due to their polar nature and strong intermolecular forces such as hydrogen bonding.


Explanation:

Carboxylic acids have high boiling points and melting points due to their polar nature, which allows for strong intermolecular forces such as hydrogen bonding. This results in a higher boiling point compared to substances of similar molar mass. Carboxylic acids are also completely miscible with water for those with one to four carbon atoms, with solubility decreasing as molar mass increases.
