Compare the steam volatility of o-nitrophenol and p-nitrophenol. Which statement is correct?

Ortho: Electronic Displacement Effect diagram 1219 Para: Electronic Displacement Effect diagram 1216

Options:

Answer:
A
Solution:

In o-nitrophenol, the adjacent and groups form an intramolecular hydrogen bond. This reduces hydrogen-bond association between molecules and makes it steam-volatile. In p-nitrophenol, intramolecular bonding between those groups is impossible; intermolecular hydrogen-bond association is stronger and volatility is lower. Therefore A is correct.
