    The order of reactivity of halides towards \[2Ag+\frac{1}{2}{{O}_{2}}\xrightarrow{{}}Ag{{O}_{2}}\] mechanism is

    A) \[2Mg+\frac{1}{2}{{O}_{2}}\xrightarrow{{}}MgO\]

    B) \[{{H}_{2}}S{{O}_{4}}\]

    C) \[\text{K},{{\text{H}}_{\text{2}}},\text{ KOH}.\text{A}l\]

    D) \[\text{Na},{{\text{H}}_{\text{2}}},\text{ NaOH},\text{Zn}\]

    Correct Answer: D

    Solution :

    The order of reactivity of halides towards \[NO_{3}^{-}\] mechanism is\[\text{Fe(I)}\,\,\text{and}\,\,\text{NO}\,\,\text{as}\,N{{O}^{+}}\] \[C=20%,H=6.67%\]reaction   is   non-stereospecific   and non-stereo selective as the attack of nucleophile is not specific and the products are a mixture of enantiomers.
