  • c)
    [Cr(CO)₆]
  • d)
    [Fe(CO)6]

Verified Answer
Among the following metal carbonyls, the C O bond order is lowest ina...
• Mn+ = 3d54s1 in presence of CO effective configuration = 3d64s0.
Three lone pair for back bonding with vacant orbital of C in CO.
• Fe0 = 3d64s2 in presence of CO effective configuration = 3d8 four lone pair for back bonding with CO.
• Cr0 = 3d54s1
Effective configuration = 3d6. Three lone pair for back bonding with CO.
• V− = 3d44s2 effective configuration = 3d6three lone pair for back bonding with CO. Maximum back bonding is present in Fe(CO)5there for CO bond order is lowest here.
