Ligands and dative bonds
Ligands and dative bonds
Transition-metal ions can accept lone pairs from surrounding ions or molecules. A ligand is an ion or molecule that donates a lone pair to the metal ion, forming a dative covalent bond.
Step-by-step lessons covering Edexcel A Level Chemistry Complex ions and ligand substitution for A Level Chemistry. Each lesson works through exam-style questions in Paper 1, Paper 2 and Paper 3 format. Build confidence with atomic structure, bonding and moles calculations early on, since these underpin the more demanding organic mechanisms, equilibrium and practical-analysis topics that dominate Year 2.
