Trans-effect (a kinetic phenomenon) indi...

Trans-effect (a kinetic phenomenon) indicates the labilisation at the trans-position during the nucleophilic substitution.
The ligand which can weaken its trans bond more is considered to have its more trans influence. Trans-effect series :
`CN^(-),COgtH^(-) gt Ph^(-) gt NO_(2)^(-),I^(-) gt Br^(-) gt Cl^(-) gt NH_(3) gt OH^(-) gt H_(2)O`
`[PtCl_(4)]^(2-) overset(NH_(3))underset(2 eq.) to "products"` :

A

`100 % cis-[Pt(NH_(3))_(2)Cl_(2)]`

B

`100 % trans-[Pt(NH_(3))_(2)Cl_(2)]`

C

Mixture of diastereomers with % trans `gt` % cis

D

Mixture of diastereomers with % cis `gt` % trans
