Acetic аcid, CH₃CO₂H, is а weаk acid (Ka = 1.8 × 10⁻⁵). Trifluоrоacetic acid, CF₃CO₂H, made by replacing the three nоn-dissociable H atoms of the methyl group with F atoms, is a borderline strong acid (Ka between 10⁻¹ and 10⁻²). Which statement best explains this several-thousand-fold increase in Ka?
