    option D Bonding modes of CO CO typically bonds in an end-on fashion through carbon as shown above. However, bridging carbonyls are not uncommon and often undergo exchange with terminal carbonyls. A variant of a bridging carbonyl is the "semi-bridging" carbonyl in which the M-CO-M bond is asymmetric rather than symmetric. Some less common bonding modes are shown below; notice that the metrical data provided in each case are consistent with a decrease in the CO bond order:
