Solution:

In metal carbonyl , metal is bonded to the ligand through carbon atoms. These compounds contain both and -bonded complexes.
-bond between metal and carbon atom is formed when a vacant hybrid bond of the metal atom overlaps with an orbital on -atom of carbon mono oxide containing a low pair of electron formation of -bond is caused when a filled orbital of the metal atom overlaps with a vacant antibonding - orbital of -atom of .
