Chemistry - ALCOHOL & ETHER Question with Solution | TestHub

$-\mathrm{O}\mathrm{C}{\mathrm{H}}_3,-\mathrm{C}{\mathrm{H}}_3$are electron donating groups so decrease the acidic character of phenols.$-\mathrm{N}{\mathrm{O}}_2,-\mathrm{C}\mathrm{N}$are electron withdrawing groups, tend to increase the acidic character. Hence acidic strength order is

p-methoxyphenol < p-methylphenol < p-nitrophenol.
