Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Carbonyl groups can be terminal or bridging between two metal atoms.
Step 2: Meaning
The structure of $[Mn_2(CO)_{10}]$ consists of two $Mn(CO)_5$ units joined by a Mn-Mn bond.
Step 3: Analysis
Each Manganese atom is bonded to 5 terminal carbonyl groups. There are no CO groups shared (bridged) between the atoms.
Step 4: Conclusion
The number of bridging carbonyls is zero. Final Answer: (B)
