Comprehension Type
Direction (Q. Nos. 16-18) 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?
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?
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
Matching List Type
Direction (Q. Nos. 19 and 20) Choices for the correct combination of elements from Column I and Column II are given as options (a), (b), (c) and (d), out of which one is correct.
