Coordination Compounds Mind Map
Coordination Compounds Mind Map (NCERT Class 12 Chemistry - Chapter 9) Coordination compounds, also known as complex compounds, are a fascinating class of molecules where a central metal atom or ion is surrounded by a fixed number of ions or molecules. These surrounding species, called ligands, donate electron pairs to the central atom, forming coordinate bonds. This chapter delves into the world of coordination compounds, exploring their structure, bonding, nomenclature, and applications. 1. Werner's Theory of Coordination Compounds: The foundation for understanding coordination compounds is laid by Alfred Werner's theory. This theory proposes the following key points: Central Atom/Ion: A metal atom or ion acts as the central entity in a coordination compound. Ligands: Ions or molecules surrounding the central atom/ion and donating electron pairs are called ligands. Common ligands include ammonia (NH3), chloride (Cl-), water (H2O), and cyanide (CN-). Coordination Number: ...
