Number of metals – metal bonds in Co₂CO₈ is ‘ x. Number of bridged carbonyl groups in Mn₂CO₁₀ is ‘ y’. x and y are respectively.

Explanation

To determine the values of x (the number of metal-metal bonds in Co₂CO₈) and y (the number of bridged carbonyl groups in Mn₂CO₁₀), we need to analyze the structures of these compounds.

Analysis of Co₂CO₈

• Structure:
  • Dicobalt Octacarbonyl (Co₂CO₈) consists of two cobalt atoms bonded to eight carbon monoxide (CO) ligands.
  • In this structure, there are No metal-metal bonds, because the cobalt atoms are coordinated only through the carbonyl ligands.

Therefore, for Co₂CO₈:

• Number of Metal-Metal Bonds (x): 0

Analysis of Mn₂CO₁₀

• Structure:
  • Dimanganese Decacarbonyl (Mn₂CO₁₀) consists of two manganese atoms bonded to ten carbon monoxide (CO) ligands.
  • In this compound, there is typically 1 bridging carbonyl group, which connects the two manganese atoms.

Therefore, for Mn₂CO₁₀:

• Number of Bridged Carbonyl Groups (y): 1

Final Answer

The combined results are:

• x = 0
• y = 1

The correct answer is: d. 0, 1
