The number of ligands which are directly bonded to the metal is known as
Options
- Aco-ordination number
- Boxidation number
- Cco-ordination sphere
- Dvalency
Correct answer
A. co-ordination number
Step-by-step solution
The number of ligand donor atoms to which the metal is directly bonded is defined as the co-ordination number of the metal in the complex. For example, in the complex ion [PtCl₆]²⁻ , the co-ordination number of platinum is 6 because it is directly bonded to six chloride ligands. Answer: co-ordination number
