    Which reagent can be used for the alkglation of aromatic nitro compounds?

    A)  Methyl sulfinyl carbanion

    B)  Methyl iodide

    C)  Dimethyl sulphate

    D)  Methyl lithium

    Correct Answer: A

    Solution :

    The \[-N{{O}_{2}}\] group is ring deactivating group. Hence, it does not favour electrophilic alkylation in benzene. Nitrobenzene undergoes nucleophilic alkylation by carbanion intermediate. Hence, methyl sulphinyl carbanion is used for the alkylation of aromatic nitro compounds.
