JEE Advanced Chemistry question

Statement 1: Ozone is a powerful oxidizing agent in comparison to O2 Statement 2: Ozone is diamagnetic but O2 is paramagnetic

(A)Assertion is True, Reason is True; Reason is correct explanation for Assertion
(B)Assertion is True, Reason is True; Reason is not correct explanation for AssertionCorrect
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is True

Answer: (B)

Solution

Ozone is indeed a much stronger oxidising agent than O2, since it readily decomposes to liberate highly reactive nascent oxygen (O3 → O2 + [O]), making Statement 1 true. It is also true that O3 is diamagnetic (all electrons paired) while O2 is paramagnetic (two unpaired electrons), making Statement 2 true as a fact.
