Optical isomers are mirror images that cannot be superimposed on one another, these are called

_____catalyst is sued for the hydrogenation of alkenes.

_________isomerism arises when the counter ion in a complex salt is itself a potential ligand and can displace a ligand which can then become the counter ion

___________isomerism arises from the interchange of ligands between cationic and anionic entities of different metal ion present in a complex.

In the formation of a complex, since the inner d orbital is used in hybridization, then such complexes are known as _________ complexes.

_________was the first to formulate his ideas about the structure of co-ordination compounds.

The splitting of degenerate levels due to the presence of ligands in a definite geometry is termed as ___________ splitting.

_________ valence are normally ionisable and are satisfied by negative ions.

__________is the co-ordination number of the complex having tetrahedral geometry.

___________theory helps to predict the geometry of a complex.
