Given below are two statements: Statement I: o-Nitrophenol is steam volatile due to intramolecular hydrogen bonding. Statement II: o-Nitrophenol has high melting point due to hydrogen bonding. In the light of the above statements, choose the most appropriate answer from the options given below:

1. Statement I is false but Statement II is true
2. Both statement I and statement II are true
3. Both statement I and statement II are false
4. Statement I is true but statement II is false

Correct answer: Statement I is true but statement II is false

Solution

o-Nitrophenol exhibits intramolecular hydrogen bonding, which allows it to be steam volatile, making Statement I true. However, its high melting point is primarily due to intermolecular hydrogen bonding, not intramolecular, rendering Statement II false.
