why o-nitrophenol is more acidic than ortho methoxyphenol - Chemistry - Haloalkanes and Haloarenes

Question

why o-nitrophenol is more acidic than ortho methoxyphenol?

Urvashi Yadav · Accepted Answer

The nitro-group is an electron-withdrawing group The presence of
this group in the ortho position decreases the electron density in
the Oâˆ’H bond As a result, it is easier to lose a
proton Also, the o-nitrophenoxide ion formed after the loss of
protons is stabilized by resonance Hence, ortho nitrophenol is a
stronger acid
On the other hand, methoxy group is an electron-releasing group
Thus, it increases the electron density in the
Oâˆ’H bond and hence, the proton cannot be given
out easily For this reason, ortho-nitrophenol is more acidic than
ortho-methoxyphenol
