10 Questions
What is the formula to calculate Crystal Field Splitting Energy (CFSE) for octahedral complexes?
CFSE = [-0.4x + 0.6y]Δo
In the context of Splitting Energy (Δ) and Pairing Energy (P), what type of complex is formed when Δ > P?
Low Spin Complex (Strong Field Ligand)
Define Cis Isomers in terms of ligand arrangement.
Cis Isomers have similar ligands at an angle of 90°.
What does the term 'Enantiomeric Pair' refer to?
A molecule that is non-superimposable on its mirror image.
Give an example of Ionisation Isomerism.
[Co(NH3)5SO4]Cl
What is the definition of Geometrical Isomers in coordination complexes?
Geometrical Isomers have different spatial arrangements due to the fixed coordination number and ligand field.
What is the significance of Pairing Energy (P) in determining the nature of a coordination complex?
P determines whether the complex will be a Low Spin or High Spin complex.
Explain the concept of Hydrate Isomerism with an example.
[Cr(H2O)5Cl]3 and [Cr(H2O)5Cl]Cl2.H2O
What does Octet Expansion refer to in coordination complexes?
Octet Expansion involves the use of empty d orbitals in the valence shell to accommodate more than 8 electrons.
Differentiate between Facial and Meridional Isomers based on ligand arrangement.
Facial Isomers have three similar ligands at an angle of 90°, while Meridional Isomers have three similar ligands forming two 90° angles and one 180° angle.
