Total number of ligand(s) which forms five membered ring \& also contains chiral centre(s). pn, en, tn, bn,
Answer:
Solution:
The ligands are:
1. pn (1,2-diaminopropane): Forms a 5-membered ring and has a chiral center.
2. en (ethylenediamine): Forms a 5-membered ring but no chiral center.
3. tn (1,3-diaminopropane): Forms a 6-membered ring, no chiral center.
4. bn (2,3-diaminobutane): Forms a 5-membered ring and has two chiral centers (or meso form).
5. DMG⁻¹ (dimethylglyoximate): Forms a 5-membered ring, no chiral center.
6. acac⁻¹ (acetylacetonate): Forms a 6-membered ring, no chiral center.
7. nta⁻¹ (nitrilotriacetate): Forms multiple 5-membered rings, no chiral center.
Ligands forming 5-membered rings with chiral centers are pn and bn.
Therefore, the total number of such ligands is 2.
