Find the number of property (ies) does change when all the 'en' ligands in are replaced by 'gly , ligands without changing oxidation state and co-ordination number of central metal ion. (i) (splitting energy) (ii) EAN value (iii) Geometrical isomers (iv) Optical isomers (v) Stereoisomers (vi) Magnetic moment (vii) Number of 'd' orbital participate in hybridisation
Answer:
Solution:
Four properties change when is converted to :
(splitting energy): Changes because 'en' has (N, N) donor atoms, while 'gly⁻' is an unsymmetrical ligand with (N, O) donor atoms.
Isomerism (GI, OI, and Stereoisomers): (symmetric type) has 0 GI, 2 OI, and 2 stereoisomers, whereas (unsymmetric type) forms facial and meridional forms, giving 2 GI, 4 OI, and 4 stereoisomers.
Unchanged properties: EAN (remains 36), magnetic moment (remains 0, low-spin ), and -orbitals in hybridization (remains 2 for ) do not alter since the coordination number (+6) and oxidation state (+3) stay the same.
