Identify the compound with highest acidic strength from following.

A. Ethanol

B. t-Butyl alcohol

C. Phenol

D. p-Nitrophenol

Correct Option is (D)

Phenols show weak acidic character while alcohols are neutral. Electron-withdrawing groups (like $- {NO}_{2}$ ) increase the acidity of substituted phenols. Hence, p-nitrophenol has the highest acidic strength among the given compound.
