Out of o-nitrophenol and p-nitrophenol, which is more volatile ? – InterviewSolution

1.	Out of o-nitrophenol and p-nitrophenol, which is more volatile ?
Answer» Solution :Ortho-nitrophenol is more VOLATILE because of intramolecular H-bonding (Chelation) whereas, the intermolecular H-bonding is present in p-nitrophenol. THUS, the p-nitrophenol is associated with the other MOLECULES through H-bonding and so it shows higher BOILING point.
