  • question_answer Which one of the following is the true covalent oxide of iodine [MP PET/PMT 1988]

    A) \[{{I}_{2}}{{O}_{4}}\]

    B) \[{{I}_{2}}{{O}_{5}}\]

    C) \[{{I}_{2}}{{O}_{7}}\]

    D) \[{{I}_{2}}{{O}_{9}}\]

    Correct Answer: B

    Solution :

    In general, higher the oxidation state, more is the covalent character of the oxide. \[{{I}_{2}}{{O}_{7}}\]&\[{{I}_{2}}{{O}_{5}}\] do not exist. \[{{I}_{2}}{{O}_{4}}\] is ionic in nature. It is infact iodyl iodate  \[{{[IO]}^{+}}{{[I{{O}_{3}}]}^{-}}\]. The only covalent oxide is \[{{I}_{2}}{{O}_{5}}\].
