Explain bonding in metal carbonyls
WebMetal carbonyls, nitrosyls, and isocyanides. The electrons are partially transferred from a d-orbital of the metal to anti-bonding molecular orbitals of CO (and its analogues). This electron-transfer (i) strengthens the metal–C bond and (ii) weakens the C–O bond. The strengthening of the M–CO bond is reflected in increases of the ... WebSolution. Synergic bonding interaction in a carbonyl complex is shown below. Carbonyl C donates lone pair of electrons to metal to form M−C σ bond. Filled d orbital of metal donates lone pair of electrons to vacant antibonding π orbital of CO to form M−C π bond.
