Co-ordination Compounds Class 12 Notes: Master Your Understanding of Coordination Compounds

Welcome to the comprehensive master notes on “Coordination Compounds” for Class 12 students! In this meticulously crafted study material, we delve deep into the fascinating world of coordination compounds, exploring their structure, bonding, properties, and applications. Coordination compounds are a class of chemical compounds in which a central metal atom or ion is bonded to a number of surrounding ligands. Ligands are atoms, molecules, or ions that can donate one or more pairs of electrons to the central metal atom. The central metal atom and the ligands form a coordination sphere, which is held together by coordinate covalent bonds.

Co ordination compounds are also known as co ordination complexes. They are a diverse and important class of compounds, with applications in catalysis, medicine, and materials science.

Examples of co ordination compounds:

• [CoCl3(NH3)3] (hexamminecobalt(III) chloride)
• [Fe(CN)6]4- (hexacyanoferrate(II) ion)
• [Ni(CO)4] (tetracarbonylnickel)
• [PtCl4]2- (tetrachloroplatinate(II) ion)
• [Cu(H2O)6]2+ (hexaaquacopper(II) ion)

Properties of co ordination compounds:

• Coordination compounds are often colored. The color of a coordination compound is due to the absorption of certain wavelengths of light by the d-electrons of the central metal atom.
• Coordination compounds are often soluble in water. The solubility of a coordination compound depends on the charge of the complex and the nature of the ligands.
• Coordination compounds can form isomers. Isomers are compounds with the same molecular formula but different structures.

Overview:

Co ordination compounds are a crucial aspect of inorganic chemistry that plays a vital role in understanding the coordination and interactions of metal ions with ligands. These compounds form an integral part of various biological processes, industrial applications, and environmental processes. Thus, a solid grasp of co-ordination compounds is essential for a holistic understanding of chemistry.
