Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A) : ICl is more reactive than \(I_2\).

Reason (R) : I-Cl bond is weaker than I-I bond.

In the light of the above statements, choose the most appropriate answer from the options given below :

1. (A) is not correct but (R) is correct

2. Both (A) and (R) are correct and (R) is the correct explanation of (A)

3. Both (A) and (R) are correct but (R) is not the correct explanation of (A)

4. (A) is correct but (R) is not correct

Best answer

Answer: 2. Both (A) and (R) are correct and (R) is the correct explanation of (A)

Key idea: interhalogen compounds are more reactive than the halogens because the bond between unlike atoms is weaker.

(A) is correct: ICl is more reactive than \(\mathrm{I_2}\). (R) is correct: the I-Cl bond is weaker than the I-I bond (less effective overlap, polar). Weaker bond breaks more easily, so (R) explains (A): option 2.
