The formula of a carbonyl complex of cobalt, (CO)n Co - Co(CO)n , in which there a single covalent Co - Co bond is:
a.Co2(CO)4
b.Co2(CO)6
c.Co2(CO)8
d.Co2(CO)10
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.
Proteins are polymers made out of amino acids. They are naturally occurring, meaning they are made by animals, plants, bugs, fungi, and other living things. A protein is actually a polyamide. So, proteins are polymers of amino acids.
