Assertion : Chlorine reacts more rapidly...

Assertion : Chlorine reacts more rapidly with `H_2` than with `D_2`.
Reason : D-Cl bond is stronger than H-Cl bond.

A

If both (A) and (R) are correct and (R) is the correct explanation of (A).

B

If both (A) and (R) are correct, but (R) is not the correct explanation of (A).

C

If (A) is correct, but (R) is incorrect.

D

If both (A) and (R) are incorrect.

Text Solution

Verified by Experts

The correct Answer is:
B
Due to isotope effect, rate of reaction of `Cl_2` with `D_2` is slower than that with `H_2`.
