Cr²⁺ vs Mn³⁺: Which Is the Stronger Reducing Agent? | d-Block Elements | JEE NEET CUET

Here is the link for detailed understanding of Standard Reduction Potential:    • Transition Elements: The Complete Thermody...   In this video, we break down a critical d-block elements question involving chromium (Cr) and manganese (Mn). We explore why ions with the same electronic configuration (d⁴) behave so differently in chemical reactions! 🔹 Key Concepts Covered: 1️⃣ Oxidation State Calculation: Step-by-step breakdown of Cr in the coordination complex [Cr(NH₃)₄Cl₂]⁺. 2️⃣ Reducing vs. Oxidizing Agents: Why Cr²⁺ acts as a reducing agent while Mn³⁺ is a powerful oxidizing agent. 3️⃣ Electronic Configurations: Understanding the stability of d³ (stable t₂g configuration) vs d⁵ (half-filled d-subshell stability). 4️⃣ JEE/NEET Tips: Why this specific concept is a favorite in competitive exams. 🔬 Deep Dive into the Chemistry: From the Crystal Field Theory (CFT) perspective: 🔥 Cr²⁺ (d⁴) loses one electron to become Cr³⁺ (d³), which provides a more stable t₂g³ configuration in aqueous solution. 🔥 Mn³⁺ (d⁴) gains one electron to become Mn²⁺ (d⁵), achieving the extra stability of a half-filled d-subshell. This difference in electronic stability explains why Cr²⁺ behaves as a reducing agent, while Mn³⁺ behaves as an oxidizing agent.
