JEE MAIN - Chemistry (2004 - No. 51)
The coordination number of central metal atom in a complex is determined by :
the number of ligands around a metal ion bonded by sigma bonds
the number of only anionic ligands bonded to the metal ion
the number of ligands around a metal ion bonded by sigma and pi- bonds both
the number of ligands around a metal ion bonded by pi-bonds
설명
The coordination number of central metal atom in a complex is equal to number of monovalent ligands, twice the number of bidentate ligands and so on, around the metal ion bonded by coordinate bonds. Hence coordination number $$=$$ no. of $$\sigma $$ bonds formed by metals with ligands
