UP Board Class 12 Chemistry – Coordination Compounds

The chapter Coordination Compounds in UP Board Class 12 Chemistry introduces students to the fascinating world of complex compounds formed between metals and ligands. These compounds play a crucial role in biological systems, industrial processes, and analytical chemistry.

Students learn essential terms like coordination number, ligands, coordination sphere, oxidation state, and Werner’s theory, which forms the foundation of coordination chemistry. The chapter explains different types of ligands—monodentate, bidentate, polydentate, and chelating agents—along with their bonding behavior.

A key highlight of the chapter is the IUPAC nomenclature, which helps students name coordination compounds accurately. Concepts like isomerism (ionization, hydration, linkage, coordination, and optical isomerism) are explained with clear examples.

The chapter also covers Valence Bond Theory (VBT) and an introduction to Crystal Field Theory (CFT), helping students understand magnetic properties, color, and stability of complexes.

Coordination compounds have real-world importance in medicines (like cisplatin), metallurgy, dyes, and qualitative analysis. This chapter is highly scoring and essential for exams like NEET, JEE, and UP Board.
