Which statement is incorrect about CO ligands? a. A CO ligand can accept electrons into its * MO; this weakens the C-O bond b. In the IR spectrum of Fe(CO)5, absorptions assigned to the CO stretching modes are at higher wavenumber than that of free c. CO ligands can adopt terminal, p2 and u3 bonding modes; the amount of back donation depends on the bonding mode d. Fluxional behaviour is common in metal carbonyl compounds, and can be investigated by 13C NMR spectroscopy

Coordination Chemistry

It is a part of chemistry, in which the study of compounds that have central atoms surrounded by molecules or ions, known as ligand, is known as coordination chemistry.
