    Comprehension Type

    Direction (Q. Nos. 6 - 8) This section contains a paragraph, describing theory, experiments, data, etc.
    Three questions related to the paragraph have been given. Each question has only one correct answer  mong the four given options (a), (b), (c) and (d).

    Passage

    When aldehydes lacking a-hydrogen is treated with concentrated solution of a strong base, Cannizaro reaction takes place. In this reaction, one molecule of aldehyde is oxidised while other is reduced. The widely accepted mechanism is

    Step II



    Q.

     What is the rate law derived from the above mechanism?

     

  • Question 7
    1 / -0.25

     

    When aldehydes lacking a-hydrogen is treated with concentrated solution of a strong base, Cannizaro reaction takes place. In this reaction, one molecule of aldehyde is oxidised while other is reduced. The widely accepted mechanism is

    Step II



    Q. 

    Which of the following observed fact establishes the correctness of the above mechanism?

     

  • Question 8
    1 / -0.25

     

    When aldehydes lacking a-hydrogen is treated with concentrated solution of a strong base, Cannizaro reaction takes place. In this reaction, one molecule of aldehyde is oxidised while other is reduced. The widely accepted mechanism is

    Step II



    Q. 

    In certain experim ental condition, rate is found to be proportional to square of concentration of base (OH- ).This indicates that
