Assertion : o -Nitrophenol is more volatile than p -nitrophenol....
Assertion : -Nitrophenol is more volatile than -nitrophenol.
Reason : Intramolecular hydrogen bonding is present in -nitrophenol while intermolecular - bonding is in -nitrophenol.
Options
- AIf both Assertion and Reason are true and Reason is the correct explanation of Assertion.
- BIf both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
- CIf Assertion is true but Reason is false.
- 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 -nitrophenol is responsible for it. But intramolecular hydrogen bonding in -nitrophenol does not effect boiling point.
