Question

Why amides and carboxylic acids have higher boiling point?

Answer 1

The explanation of higher boiling point of amides or carboxylic acid is explained below:

• Carboxylic acid have higher boiling point than rest of the organic compounds of comparable molecular weight because of the presence of $\mathrm{H}$- Bonding.
• The formation of dimer through $\mathrm{H}$- Bonding makes them one of the most stable and least volatile organic compound

• Amides also have the high boiling point of all the acidic derivatives. The reason is again due to $\mathrm{H}$-bonding between the Oxygen atom of the amide and the hydrogen atom of the other amide.

• Therefore, the explanation of higher boiling point of amides is explained in above points.
