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 1 - <p>(A) is true but (R) is false.</p>
Option 2 - <p>(A) is false but (R) is true</p>
Option 3 - <p>Both (A) and (R) are true but (R) is the true explanation of (A).</p>
Option 4 - <p>Both (A) and (R) are true and (R) is not the true explanation of (A).</p>

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.
