What do you mean by werner's theory of coordination compound?

Answer 1

Hey !!

WERNER'S THEORY OF COORDINATION COMPOUND

Werner he explained about the nature bonding complexes of the coordination compounds. The brief outlines of Werner's Theory are as : Metal shows two different kinds of valencies.

• Primary Valencies :- They are satisfied by anions and equal to the oxidation state of the metal.

• Secondary Valencies :- They are satisfied either by oppositely charged ions or neutral molecules and sometimes by cationic groups. Secondary valencies are equivalent to coordination number and they are directed in space in specific number around each central metal atom within the lattice.

GOOD LUCK !!

Answer 2

The important postulates of Werner's theory are: The central metal or the metal atoms in coordination compounds show two types of valency. They are the primary and secondary valency. ... A negative ion satisfies the primary valency. On the other hand, a negative ion or neutral molecules satisfy secondary valencies.
