    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: The oxidation of ketone by perbenzoic acid gives esters. Reason: Perbenzoic acid oxidises because of the release of nascent oxygen on dissociation.

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

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

    C) If Assertion: is true but Reason: is false

    D) If both Assertion: and Reason: are false

    Correct Answer: C

    Solution :

    \[C{{H}_{3}}COC{{H}_{3}}\xrightarrow{{{C}_{6}}{{H}_{5}}C{{O}_{3}}H}\underset{ester}{\mathop{C{{H}_{3}}COOC{{H}_{3}}}}\,\]                                               \[+{{C}_{6}}{{H}_{5}}COOH\] The reaction is not because of nascent oxygen. Hence, Reason: is false.
