Why is p-nitrophenol less volatile than o-nitrophenol?
Options
- ADue to intramolecular hydrogen bonding
- BDue to intermolecular hydrogen bonding
- CDue to resonance stabilisation
- DDue to dipole-dipole interactions
Correct answer
B. Due to intermolecular hydrogen bonding
Step-by-step solution
Para-nitrophenol forms intermolecular hydrogen bonds between molecules, making it less volatile compared to ortho-nitrophenol.
