Linkage Isomerism Explained: Why Red & Yellow Co(III) Complexes Are Different geochemist 2025 1 (b)

Описание: 🧪 Struggling with coordination chemistry isomerism? In this tutorial, we break down linkage isomerism using the classic example of [Co(NH₃)₅ONO]²⁺ (red) and [Co(NH₃)₅NO₂]²⁺ (yellow) complexes.

📚 What You'll Learn:
✅ What is linkage isomerism?
✅ Why nitrite (NO₂⁻) is an ambidentate ligand
✅ How bonding through O vs N creates different properties
✅ Real exam question solution (Combined Geo-Scientist 2025)
