Give Reasons: Cr2+ Is A Strong Reducing Agent Whereas Mn2+ Is Not [Cr=24 Mn=25]

The reducing agent is a compound which itself gets oxidized.

Cr2+ better reducing agent, but Mn3+ is a better oxidizing agent because:

Cr2+ is the strongest reducing agent. It has a d4 configuration.

While acting as a reducing agent, it gets oxidized to Cr3+ and acquires a d3 configuration.

This d3 configuration can be written as a t32g configuration, which is a more stable configuration.

Mn3+ has a d4 configuration.

It acts as an oxidizing agent and gets reduced to Mn2+ and acquires d5 configuration.

This has an exactly half-filled d-orbital and has extra stability.
