2022 · Q90

NEETChemistryChemical Bonding and Molecular StructureMCQ+4 / −1

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

Assertion (A) : ICI is more reactive than I2

Reason (R) : I-CI 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
    Both (A) and (R) are correct and (R) is the correct explanation of (A).
  2. B
    Both (A) and (R) are correct but (R) is not the correct explanation of (A).
  3. C
    (A) is correct but (R) is not correct.
  4. D
    (A) is not correct but (R) is correct.

Correct answer: A

In general, interhalogen compounds are more reactive than halogens (except fluorine). This is because X - X' bond in interhalogens is weaker than X - X bond in halogens excepts F - F bond. Therefore I-Cl is more reactive than I2 because of weaker I - Cl bond then I - I bond.
