Question

Are the ligand labels La (Scheme 1) ad L1 (Table 2) consistent? How did you arrive at your answer? (Note: Lb is L2 and Lc is L3) Table 2: Calculated geometric parameters of SiO2 A and complexes B-E, Gibbs free energies ( G [kcal mol 1) for the formation of complexes (B-E), and electronic charges (Q(SiO2)) of the Sio2 fragment in complexes B-E.

Explanation / Answer

Yes the ligands are capable of doing this because u can't get any Lewis acid without extraxtex
