Chemical Shift of C_{6}H_{8} ligand in [ (η^6-C_{6}H_{6})Cr(CO)_5 ]
- Expected Chemical Shift:
- The expected chemical shift of the C_{6}H_{8} ligand in the 'H NMR spectrum of [ (η^6-C_{6}H_{6})Cr(CO)_5 ] would be different from that of free benzene due to the coordination with the metal center.
- Possible Chemical Shift Values:
- (a) 4.5, disruption of ring current
- (b) 9.0, inductive effect
- (c) 7.2
- (d) 2.5, combination of inductive effect and disruption of ring current
- Explanation:
- The chemical shift of the C_{6}H_{8} ligand in [ (η^6-C_{6}H_{6})Cr(CO)_5 ] is expected to be different from that of free benzene due to the influence of the metal center and the surrounding ligands.
- The presence of the chromium atom and the carbonyl ligands can affect the chemical environment of the C_{6}H_{8} ligand, leading to a different chemical shift value.
- The disruption of the ring current and the inductive effect of the ligands can also contribute to the observed chemical shift in the 'H NMR spectrum.
- Conclusion:
- The expected chemical shift of the C_{6}H_{8} ligand in [ (η^6-C_{6}H_{6})Cr(CO)_5 ] cannot be definitively determined based solely on the information provided. The actual chemical shift value would depend on the specific coordination environment and electronic effects in the complex.
