N aqueous solutions, HF is a much weaker acid than HCl. However, when combined with Lewis acids, fluorinated systems make much stronger superacids than chlorinated ones. Which of the following best accounts for this phenomenon?
A. Aqueous, solvated F- ions are more stable in aqueous media than Cl- ions.
B. F- forms very stable complex anions through strong bonding to Lewis acids.
C. The basicity of the Cl- ion hinders its inclusion in complex anions.
D. The larger size of the Cl- anion sterically prevents its inclusion in the complex anion with a metal like Sb.
