    Which of the following is most acidic       [CPMT 1999]

    A)                 Phenol 

    B)                 Benzyl alcohol

    C)                 m-chlorophenol              

    D)                 Cyclohexanol

    Correct Answer: C

    Solution :

                    Benzyl alcohol and cyclohexanol are not acidic while phenol and m-chlorophenol are acidic due to presence of electron withdrawing groups like \[-N{{O}_{2}},\,\,-Cl,\,\,-CN\]increases the acidic character of phenols. Hence, m-chlorophenol is more acidic than phenol.
