    Direction for: In each of the following questions a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements mark the correct answer as

    Assertion: Ozone is powerful oxidising agent in comparison to \[{{O}_{2}}\]. Reason: Ozone is diamagnetic but \[{{O}_{2}}\], is paramagnetic.

    A) If both Assertion and Reason are true and Reason is the correct explanation of Assertion.

    B) If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

    C) If Assertion is true but Reason is false.

    D) If both Assertion and Reason are false.

    Correct Answer: B

    Solution :

    Ozone is a powerful oxidising agent next to fluorine. It is much stronger oxidising agent than oxygen because on easy decomposition it forms nascent oxygen. \[{{O}_{3}}\xrightarrow{{}}{{O}_{2}}+[O]\] It is also true that \[{{O}_{3}}\] diamagnetic while \[{{O}_{2}}\] is paramagnetic.
