    Which chloro derivative of benzene, would undergo hydrolysis most readily with aqueous KOH?

    A)  

    B)  

    C)  

    D)  

    Correct Answer: D

    Solution :

    Hydrolysis of an halide is nucleophilic substitution reaction, which is possible in aryl halides only when some powerful electron   withdrawing groups (like \[--N{{O}_{2}},\]\[--COOH\] etc.) are attached to especially o- and p-positions. Thus 2, 4, 6-trinitrochloro benzene will undergo hydrolysis (aq. KOH) most readily as it has \[3-{{e}^{-}}\]-withdrawing groups.
