JEE Main Chemistry question

Statement 1: Equivalent mass of is equal to one third of its molecular mass when it acts as an oxidising agent in an alkaline medium Statement 2: Oxidation number of Mn is in

(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

In alkaline medium is reduced to , a 3-electron change, so the equivalent mass is — Statement 1 is true. Statement 2 (Mn is in ) is also true, but this oxidation state is the same in every medium, whereas the equivalent
