alleryChelate complexes tend to be more stable than similar complexes with unidentate ligands. This effect is called
ASteric effect
BTrans effect
CChelate effect
DInductive effect
Answer & Solution
Correct answer: C. Chelate effect
1. A chelate ligand uses two or more donor atoms simultaneously to bind one metal.
2. The chelate ring formed increases thermodynamic stability.
3. This enhanced stability is termed the chelate effect.
4. Trans effect refers to labilisation of the ligand trans to a strong sigma-donor in Pt(II) chemistry.
