The number of bridging \(CO\) ligands and \(Co-Co\) bonds in \(Co_2(CO)_8\), respectively are:
- 0 and 2
- 2 and 0
- 4 and 0
- 2 and 1
The Correct Option is D
Approach Solution - 1
Explanation:
Given:Organometallic compound : \(Co_2(CO)_8\) We have to find the number of bridging \(CO\) ligands and \(Co-Co\) bond.
The structure of \(Co_2(CO)_8\) is:
The there are two \(CO\) bridging ligands and one \(Co-Co\) bond.
\(\text{Hence, the correct option is (D):}\) \(2 \;and \;1\)
Approach Solution -2
Ans: \(Co_2(CO)_8\) is a cobalt carbonyl complex, in this there are two bridging \(CO\) ligands and one \(Co-Co\) bond. In the compound there are four \(CO\) ligands, of these two of them are the bridging ligands. They are called bridging ligands because they bridge between the two cobalt atoms.
On the other hand, there is only one \(Co-Co\) bond in the complex. The two cobalt atoms present are connected by a single covalent bond.
