Question

Give reasons:
p-nitro phenol is more acidic than p-methyl phenol.

Answer 1

Nitro group is a electron withdrawing group. So it reduces electron density on the benzene and hence benzene abstracts electron from H and releases it as $H_2$.

But Methyl is a Electron-releasing group and hence it increases the electron density of benzene and hence benzene does not abstract electron from H atom

So, p-nitro phenol is more acidic than p-methyl phenol
