  • question_answer
    Among the members of V A group (N, P, As, Sb and Bi), which of the following properties shows an increase as we go down from nitrogen to bismuth [CPMT 1982]

    A) Stability of +3 oxidation state

    B) Reducing character of hydrides

    C) Electronegativity

    D) Acidic nature of the pentoxide

    Correct Answer: A

    Solution :

      Stability of + 3 oxidation states increases on account of inert pair effect. Reducing character of hydrides increases down the group because bond dissociation energy decreases down the group.
