Q. The coordination number of a central metal atom in a complex is determined by
A) The number around a metal ion bonded by pi-bonds
B) The number of only anionic ligands bonded to the metal ion
C) The number of ligands around a metal ion bounded by sigma and pi-bonds both
D) The number of ligands around a metal ion bonded by sigma bonds
Explanation
(d)
The number of atoms of the ligand that are directly bounded to the central metal atom or ion by coordinated bond is known as the coordination number of the metal atom or ion. Coordination number of metal =number of $\sigma$ bonds formed by metal with ligand
