Long Answer TypeWhat is meant by stability of coordinate compound in solution? State the factors which govern stability of complexes.
Short Answer TypeHow does the metal carbonyls gain stability although CO is a weak donor?
The metal -carbon bond in metal carbonyls posses both σ and π character. The M–C σ bond is formed by the donation of lone pair of electrons on the metal. The M–C π bond is formed by the donation of a pair of electrons from a filled d orbital of metal into the vacant antibonding π* orbital of carbon monoxide. The metal to ligand bonding creates a synergic effect which strengthens the bond between CO and the metal.
