Question

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): $ICl$ bond is weaker than $I-I$ bond.
In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Both (A) and (R) are correct but (R) is not the correct explanation of (A).
• B. (A) is not correct but (R) is correct.
• C. Both (A) and (R) are correct and (R) is the correct explanation of (A).
• D. (A) is correct but (R) is not correct.

Answer 1

The correct option is C Both (A) and (R) are correct and (R) is the correct explanation of (A).

$I_2$ forms covalent bond which is more stronger than inter-halogen compound and weak bonds are obviously more reactive than stronger bond
$\therefore ICl$ is more reactive than $I_2$ as $I_2$ forms stronger bond than $ICl$.
