Concept explainers

Organometallic compounds of d-block elements

The transition metals can form complexes since they have vacant d orbitals. They are also termed Coordination compounds. The organometallic compounds of the transition metals could be used as catalysts as well as reagents. For example, organocadmium, organozinc, organocopper, Grignard are used as the reagents for several reactions. Most of the complexes of organo transition metals are used as catalysts for many organic transformation reactions.

When Alfred Werner was developing the field of coordinationchemistry, it was argued by some that the opticalactivity he observed in the chiral complexes he hadprepared was due to the presence of carbon atoms in themolecule. To disprove this argument, Werner synthesizeda chiral complex of cobalt that had no carbon atoms in it,and he was able to resolve it into its enantiomers. Design acobalt(III) complex that would be chiral if it could be synthesizedand that contains no carbon atoms. (It may not bepossible to synthesize the complex you design, but we willnot worry about that for now.)
