Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): Heavy water is used for the study of reaction mechanism.
Reason (R): The rate of reaction for the cleavage of O-H bond is slower than that of O-D bond.
Choose the most appropriate answer from the options given below:

Option 4 -
Both (A) and (R) are true and (R) is not the true explanation of (A).

Correct Option - 1
Detailed Solution:Heavy water (D2O) is used to study reaction mechanism. O-H bond energy is less than O-D, hence it will produce fast reaction than O-D. Here assertion is true but Reason is false.
