Assertion: Boiling and melting points of amides are higher than corresponding acids. Reason: It is due to strong intermolecular hydrogen bonding in their molecules.

(A) If both assertion and reason are true and reason is a correct explanation of the assertion (B) If both the assertion and reason are true but the reason is not a correct explanation of the assertion (C) If the assertion is true but the reason is false (D) If both the assertion and reason are false

Amides are R - CONH 2 Acid R - COOH Due to the presence of - NH 2 group in amides there is stronger hydrogen bonding between the amide molecules than between the acid molecules. Some acids are rather present in dimers form due to the presence of intra molecular hydrogen bonding. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/4e1c0cc8604a022ce2d65f9664442be5-.png" />

Q. 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 true and reason is a correct explanation of the assertion

If both the assertion and reason are true but the reason is not a correct explanation of the assertion

If the assertion is true but the reason is false

If both the assertion and reason are false

Amides are $R - CON H_{2}$

Acid $R - COO H$

Due to the presence of $- N H_{2}$ group in amides there is stronger hydrogen bonding between the amide molecules than between the acid molecules. Some acids are rather present in dimers form due to the presence of intra molecular hydrogen bonding.
