QJEEM12Chc36e: JEE Main 2012 Chemistry - Class 12 JEEM12Chc36e Solution: Ortho–Nitrophenol is less soluble in water than p– and m–…
Ortho–Nitrophenol is less soluble in water than p– and m– Nitrophenols because :
Multiple Choice Options
Ao–Nitrophenol is more volatile in steam than those of m – and p–isomers
Bo–Nitrophenol shows Intramolecular H–bonding
Co–Nitrophenol shows Intermolecular H–bonding
DMelting point of o–Nitrophenol is lower than those of m–and p–isomers.
Step-by-Step Verified Solution
As in ortho-Nitrophenol H of -OH is already in Intra-moleculer H Bond and become stable so it will not perticipate in H bonding with H2O by breaking this H bonding. That is why solublity of Ortho–Nitrophenol is less in water.
para– and meta– Nitrophenols both shows inter-moleculer H bonding with H2O. That is why both are more soluble in water.
