Assertion : o -Nitrophenol is more volatile than p -nitrophenol. Reason : Intramolecular hydrogen bonding is present in o -nitrophenol while intermolecular H - bonding is in p -nitrophenol.

Options

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

Correct answer

A. If both Assertion and Reason are true and Reason is the correct explanation of Assertion.

Step-by-step solution

p-Nitrophenol has higher boiling point than o-nitrophenol, because intermolecular hydrogen bonding present in p -nitrophenol is responsible for it. But intramolecular hydrogen bonding in o -nitrophenol does not effect boiling point.
