Give reasons fer the following :
o-nitrophenol is more acidic than o-methoxyphenol.

Explanation

The -`NO_(2)` group shows -R and I effects. These effects decrease the electron density in the O-H bond. Due to low electron density, loss of proton becomes easy. After losing one proton, `o^(-)` nitrophenoxide becomes more stable by resonance.

But in ortho-Methoxy phenol, alkyl group shows +I effect. This effect increases the electron density in the O-H bond. It makes the removal of proton more difficult.

Here, o-methoxyphenoxide ion is left after removal of proton which is unstable in nature.
