Answer:
C
Explanation:
.
The carbonyl complex of cobalt having a single Co-Co bond is CO2(CO)8 Metal Carbonyls have synergic bonding interactions. The metal carbon bond in metal carbonyl has both s and p characters.
The Metal-Carbon bond formed by donation of lone pair from the carbonyl carbon into vacant orbital of metal.π Bond between metal and carbon is formed by the donation of a pair of electrons from a filled d orbital of metal into the vacant anti bonding π∗ orbital of carbon monoxide. This bonding makes the bond very strong.
Correct option is C.
