Question

Given below are two statement:

Statement I: o-Nitrophenol is steam volatile due to intramolecular hydrogen bonding.
Statement II: o-Nitrophenol has high melting point due to hydrogen bonding.

• A. Both Statement I and Statement II are false
• B. Statement I is false but Statement II is true
• C. Both Statement I and Statement II are true
• D. Statement I is true but Statement II is false

Answer 1

The correct option is D Statement I is true but Statement II is false


o-Nitrophenol is steam volatile due to intramolecular hydrogen bonding.
But m-Nitrophenol has more melting point due to its symmetry. Melting point depends upon packing efficiency of the molecule not on hydrogen bonding.
