Assertion :- Cr^(+2) is a reducing agent and Mn^(+3) is oxidising agent. Reason :- Mn^(+3) has d^(5) configuration.

Assertion : Cr^(2+) is reducing and Mn^(3+) is oxidising. Reason : Cr^(2+) and Mn^(3+) have d^4 configuration.

The ion Cr^(2+) is redusing agent while that of Mn^(3+) is an oxidising agent though both have 3d^(4) configuration. This is because

With 3d^(4) configuration, Cr^(2+) acts as a reducing agent but Mn^(3+) acts as an oxidising agent. Explain.

Four statement of Cr and Mn are given below. (P). Cr^(2+) and Mn^(3+) have the same electronic configuration. (Q). Cr^(2+) is a reducing agent while Mn^(3+) in an oxidizing agent. (S). Both Cr and Mn are oxidizing agent. The correct statement are:

Why is Cr^(2+) reducing and Mn^(3+) oxidising when both have d^(4) configuration ?

Which of the following is true for the species having 3d^(4) configuration? (A) Cr^(2+) is reducing in nature. (B) Mn^(3+) is oxidising in nature. (C) Both (A) and (B) (D) None of these
