The coordination number of a central metal atom in a complex is determined by:

A

the number of ligands around a metal ion bonded by sigma bonds

B

the number of ligarnds around a metal ion bonded by `pi`-bonds

C

the number of ligands around a metal ion bounded by sigma and pi bonds both

D

the number of only anionic ligands bonded to the metal ion.

Text Solution
