Types of Bonding in Transition Metal Systems and Simple Ligands

The video tutorial explores transition metals, focusing on their interaction with ligands. It covers types of metal-ligand bonds, including covalent and dative bonds, and explains the concept of back bonding. The tutorial also discusses the geometries of metal complexes and introduces common ligands, such as hydride, halide, and chalcogen, detailing their bonding mechanisms. Advanced ligands like nitrosyl and carbonyl are also examined, highlighting their unique bonding properties.
