  • question_answer
    Arrange the following ions in the order of decreasing\[~X-O\] bond length, where X is the central atom

    A) \[ClO_{_{4}}^{-},SO_{4}^{2-},PO_{4}^{3-},SiO_{4}^{-}\]

    B) \[SiO_{4}^{4-},PO_{4}^{3-},SO_{4}^{2-},ClO_{4}^{-}\]

    C) \[SiO_{4}^{4-},PO_{4}^{3-},ClO_{4}^{-},SO_{4}^{2-}\]

    D) \[SiO_{4}^{4-},SO_{4}^{2-},PO_{4}^{3-},ClO_{4}^{-}\]

    Correct Answer: B

    Solution :

    [b] More will be the electronegativity of X, lesser will be the bond length of \[X-O\] bond.
