Chlorine is less electronegative than oxygen, is larger so its electrons should donate more easily since the nucleus has a weaker hold on the valence electrons.
Witryna4 kwi 2024 · The correct order of Lewis acidic character is BF3 < BC13 < BBr3 < Bl3. A Lewis acid is defined as the chemical compound which contains an empty orbital that can add an electron pair from a Lewis base to form a Lewis adduct.
