what are four postulate of werners theory

Answer 1

Heya Mate!!


Here is the answer
=================

Four postulates on Werners theory
------------------------------------------------------

♢The central metal or the metal atoms in coordination compounds show two types of valency. They are the primary and the secondary valency.
♢The primary valency relates to the oxidation state and the secondary valency relates to the coordinate number.
♢The number of secondary valences is fixed for every metal atom. It means that the coordination number is fixed.
♢The metal atom works towards satisfying both its primary and secondary valencies. A negative ion satisfies the primary valency. On the other hand, a negative ion or neutral molecules satisfy secondary valencies.

The Main Postulate of Werners theory are:

1. In coordination compound metal show two types of valencies- primary and secondary.

2. The primary valency are normally ionisable and are satisfied by negative ions.

3. The secondary valency are non ionisable. These are satisfied by neutral ions or negative ions.

4. The ions bound by secondary valency to the metal have characteristic spatial arrangement corresponding to different coordination numbers.
