Q.
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:
A) (A) is not correct but (R) is correct.
B) Both (A) and (R) are correct and (R) is the correct explanation of (A).
C) Both (A) and (R) are correct but (R) is not the correct explanation of (A).
D) (A) is correct but (R) is not correct.
Explanation
[Solution] ICl is more reactive than $I_2$ because the I-Cl bond is polar. However, the I-Cl bond (about 211 kJ/mol) is stronger, not weaker, than the I-I bond (about 151 kJ/mol), so (R) is incorrect. Answer (2).
