NEET2002ChemistryChemical Bonding and Molecular StructureActual

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

Options

  1. AIf both the assertion and reason are true and reason is a correct explanation of the assertion.
  2. BIf both assertion and reason are true but assertion is not a correct explanation of the assertion.
  3. CIf the assertion is true but the reason is false.
  4. DIf both assertion and reason are false.

Correct answer

A. If both the assertion and reason are true and reason is a correct explanation of the assertion.

Step-by-step solution

Amides are R- CONH ₂ Acids are 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.
