The correct statements about `Cr^(2+)` and `Mn^(3+)` is (are) (Atomic numbers of Cr-24 and Mn=25]

Options

A. `Cr^(2+)` is a reducing agent.
B. `Mn^(3+)` is an oxidizing agent.
C. Both `Cr^(2+)` and `Mn^(3+)` exhibit `d^4 `electronic configuration.
D. When `Cr^(2+)` is used as a reducing agent, the chromium ion attains `d^5 `electronic configuration.

Answer

A, B, C

Explanation

`A) Cr^(3+) ` is more stable than ` Cr^(2+) `, thus ` Cr^(2+)` acts as reducing agent .
B) B) `Mn^(2+)` is more stable than `Mn^(3+)` thus, `Mn^(3+)` act as an oxidizing agent.
C) Both `Cr^(2+)` and `Mn^(3+)` exhibit `d^4` electronic configuration,
