Question

What are the postulates of werner theory class 12th?

Answer 1

1-acc to this theory, each co-ordination compound having two types of valency known as primary and secondary valency.
2-the primary valency is only satisfied by -'ve charge atom and secondary valency is satisfied by either -'ve or neutral ligand.
3-the primary valency is ionisable while secondary valency is non-ionisable .
4-secondary valency is also known as co-ordination number or auxiliary valency.


i hope that enough

Answer 2

Answer:

Postulates of werner theory :

➡️In coordination Compounds metal show 2 type of linkages primary and secondary

➡️ The primary Valence are normally ionisable and are satisfied by negative ions

➡️The secondary valances are non ionisable. These are satisfied by neutral molecules or negative ions.

➡️Secondary valence are directional, whereas primary valances are not directional.
