"WebJul 15, 2024 · The basicity of a carbonyl group can be studied from the acidity of its protonated form. The higher the acidity of the protonated form, the lower the starting carbonyl's basicity. The higher the participation of the third resonance form, the more stable (less acidic) the protonated form of a carbonyl group. " - Carbonyl basicity
