The difference between a weak field ligand and a strong field ligand is:
1. | Weak field ligands cause higher splitting in the d orbitals than strong field ligands. |
2. | Weak field ligands cause lower splitting in the d orbitals than strong field ligands. |
3. | Strong field ligands did not form a complex with metal ion. |
4. | None of the above. |
The crystal field splitting energy is:
1. | The heat of formation between the two levels (eg and t2g) |
2. | The combined pairing energy of the two levels (eg and t2g) |
3. | The combined energy of the three levels in octahedral |
4. | The combined energy of the two levels ( and ) |
[Cr(NH3)6]3+ is paramagnetic ,while is diamagnetic because:
1. | Electrons in the 3d orbitals remain unpaired in |
2. | Electrons in the 3d orbitals remain unpaired in [Cr(NH3)6]3+ |
3. | Electrons in the 3p orbitals remain unpaired in [Cr(NH3)6]3+ |
4. | Electrons in the 3p orbitals remain unpaired in |
The greater value of the stability constant of complex salt indicates:
1. The greater proportion of products.
2. The greater proportion of reactants
3. Lesser concentration of catalyst at equilibrium
4. All of the above
