Assertion Chlorine reacts more rapidly with \( \boldsymbol{H}_{2}, \) in comparision to \( \boldsymbol{O}_{\mathbf{2}} \) Reason \( D-C l \) bond is stronger in comparison to \( H-C l \) bond

1. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
2. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
3. Assertion is correct but Reason is incorrect
4. Both Assertion and Reason are incorrect

Correct answer: Assertion is correct but Reason is incorrect

Solution

Chlorine reacts faster with H2 than with O2 because the H–H bond is relatively easier to break than the very strong O=O bond, so the H2 reaction has a lower activation barrier. The reason is incorrect because the Cl–Cl bond is not stronger than the H–Cl bond; in fact, H–Cl is stronger.
