Statement-I : Water is more acidic than ROH 

Statement-II : HO^- is less stbale than  RO^-

greater the stability of the anion obtained by deprotonation of aspecies, greater the acidic strength of the species.

$\begin{array}{l}{\mathrm{H}}_2\mathrm{O}\stackrel{ }{\rightleftharpoons }{\mathrm{HO}}^{-}+{\mathrm{H}}^{+}\\ \mathrm{ROH}\stackrel{ }{\rightleftharpoons }{\mathrm{RO}}^{-}+{\mathrm{H}}^{+}\end{array}$

Stability of HO^- > RO^- 

In alkoxide ion (RO^-) negative charge accumulation occurs due to the +I effect of – R group.

$\therefore$ it is less stable tnan HO^-

Thus acidic strength of H₂O > ROH.
