    The strongest ortho-para and strongest mete-directing groups respectively, are

    A)  \[-N{{O}_{2}}\] and\[-N{{H}_{2}}\]

    B)  \[-CON{{H}_{2}}\] and\[-N{{H}_{2}}\]

    C)  \[-N{{H}_{2}}\] and\[-CON{{H}_{2}}\]

    D)  \[-X\] and\[-CON{{H}_{2}}\]

    E)  \[-N{{H}_{2}}\] and\[-N{{O}_{2}}\]

    Correct Answer: E

    Solution :

                    The strongest ortho-para and strongest meta-directing groups are \[-N{{H}_{2}}\]and\[-N{{O}_{2}}\] respectively because the electron donating ability of \[-N{{H}_{2}}\] is higher than others and electron withdrawing ability of \[-N{{O}_{2}}\] group is higher than others.
