    Which of the following is not correct?

    A)  Hydrolysis of \[NC{{l}_{3}}\] gives \[N{{H}_{3}}\]and \[HOCl\]

    B)  \[N{{H}_{3}}\]is less stable than \[P{{H}_{3}}\]

    C)  \[N{{H}_{3}}\] is a weak reducing reagent compared to \[P{{H}_{3}}\]

    D)  Nitric oxide in solid state exhibits diamagnetic property

    Correct Answer: B

    Solution :

    Among V A group hydrides, the stability decreases in going down the group ie, \[N{{H}_{3}}>P{{H}_{3}}>As{{H}_{3}}>Sb{{H}_{3}}>Bi{{H}_{3}}\] It is due to the increasing bond length down the group.
