What is piback bonding?

Answer»

SOLUTION :(i)In metal carbonyls , the bond between metal atom and the carbonyl ligand consists of two components
(ii) The first component is an electron pair donation from the carbon atom of carbonyl ligand into a vacant d-orbital of central metal atom.
(ii) This electron pair donation forms ` M overset(sigma" bond ")leftarrowCO ` sigma bond. This sigma bond formation increases th electron dentisity in metal d ORBITALS and makes the metal electron RICH .
(IV) In order to compensate for this increased electron density ,a field metal d-orbital interacts with the empty `pi*` orbital on the carbonyl ligand and transfers the added electron density back to the ligand.
