Write the postulates of Werner’s theory of coordination compounds.
Answers
Explanation:
Postulates of Werner's Theory The central metal or the metal atoms in coordination compounds show two types of valency. ... A negative ion satisfies the primary valency. On the other hand, a negative ion or neutral molecules satisfy secondary valencies. The secondary valencies point towards a fixed position in space.
Answer:
( a ) A metal shows two kinds of valencies viz primary valency and secondary valency.Negative ionssatisfy primary valenciesand secondaryvalencies are filled by bothneutral ions and negative ions.
( b ) A metal ion has a fixed amount of secondary valencies about the central atom. These valenciesalso orient themselves in a particular direction in the space provided to the definite geometry of the coordination compound.
( c ) Secondary valencies cannot be ionized , while primary valencies can usually be ionized.
