MCQ
Assertion : Boiling and melting points of amides are higher than corresponding acids.
Reason : It is due to strong intermolecular hydrogen bonding in their molecules.
  • ✓
    If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
  • B
    If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
  • C
    If the Assertion is correct but Reason is incorrect.
  • D
    If both the Assertion and Reason are incorrect.

Answer

Correct option: A.
If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
a
The amides generally have high boiling points and melting points. It is due to strong intermolecular hydrogen bonding in their molecules.

These characteristics and their solubility in water result from the polar nature of the amide group and hydrogen bonding.

Hence, both assertion and reason are correct and reason is the correct explanation for assertion.
