1.	Explain the following behaviours:Ortho-nitrophenol is more acidic than ortho-methoxyphenol.
Answer» Nitro being the electron withdraning group stabilises the phenoxide ion. Detaited Answer Nitro-group is an electron-withdrawing group. The presence of this group in the ortho position decreases the electron density in the O-H bond resulting in easier loss of proton. The o-nitrophenoxide ion formed after the loss of protons is stabilsed by resonance. Hence, orthonitrophenol is a stronger in acid. Whereas, methoxy is an electron-releasing the b-u bond. Thus, proton is released easily. Thus ortho-nitrophenol is more acidic that orthowhereas methoxyphenol.
