Verified By Collegedunia
The Correct Option is A
Solution and Explanation
In ortho and para-nitrophenol, ortho-nitrophenol has intramolecular H-bonding. So, it has lower boiling point. Intermolecular H-bonding more strong then intramolecular H-bonding. Whereas para-nitrophenol has intermolecular H-bonding. So, it has higher boiling point. Due to difference in boiling points ortho and para-nitrophenol can be separated from each other by distillation.
