Mononuclear Carbonyl Complexes
- A mononuclear carbonyl complex consists of a single metal center bonded to carbon monoxide (CO) ligands.
- Not all transition metals form stable mononuclear carbonyl complexes due to differences in their electronic configurations, size, and ability to back-donate electron density to the CO ligands.
EXPLANATION:
- Fe: Iron forms a well-known mononuclear carbonyl complex, Fe(CO)5, which is stable and commonly studied.
- Ni: Nickel forms the mononuclear carbonyl complex Ni(CO)4, which is also stable and used in various applications.
- Mn: Manganese forms the mononuclear carbonyl complex Mn(CO)5, where manganese is in the +1 oxidation state (Mn+).
- All the metals listed (Fe, Ni, Mn) form stable mononuclear carbonyl complexes.
CONCLUSION:
The correct answer is None of these.
