Factors Affect The Rate Of Substitution

Size of Metal ion

Charge on metal ion

Size of incoming ligand Charge on the incoming ligand

Size charge on leaving group

Trans effect

Size of Metal ion

Large size so that the association !ith incoming

ligand !ill be easy

7/24/2019 inorg- square planar complex.ppt

14/20

Charge on metal ionCharge on metal ion should be greater !hich

!ill assist in association !ith incoming

ligand

15/20

Size of incoming ligand

Size of incoming ligands be smaller so that it

can approach the metal ion very closely

easily

16/20

Charge on the incoming ligand

To have a ma"imum interaction bet!een

incoming ligand metal ion charge on

ligand should be greater

Size charge on leaving groupLeaving group should be small to ma#e itsdeparture easy
