Question

Among the following which is the strongest oxidizing agent?

Options

• Mn⁺³

• Fe⁺³

• Ti⁺³

• Cr⁺³

Answer 1

Mn⁺³

Explanation:

The strength of an oxidising agent depends on its tendency to gain electrons (i.e., to get reduced). Among the given ions, Mn³⁺ has the highest tendency to get reduced to Mn²⁺. This is because the \[\ce{Mn^{3+} -> Mn^{2+}}\] change leads to a stable half‑filled d⁵ configuration. Hence, Mn³⁺ readily accepts an electron and acts as a strong oxidising agent.
