11.2.1 Valence Bond Theory The main points of valence bond theory: 1.Central metal ion(M):having empty orbits Ligands(L):having lone electron pairs The metal-ligand bonds are coordination covalent bond M<L. 2.The metal-ligand bonds are formed by hybrid orbits. 3.The different types of hybridization determine the structure of coordination compounds
The main points of valence bond theory ： 1. Central metal ion(M) ：having empty orbits Ligands(L) ：having lone electron pairs The metal-ligand bonds are coordination covalent bond M ← L. 2. The metal-ligand bonds are formed by hybrid orbits. 3. The different types of hybridization determine the structure of coordination compounds. 11.2.1 Valence Bond Theory
