WebMar 20, 2024 · The positive charge could either be stabilized by resonance or electron donating groups. In case of benzaldehyde, the positive charge is highly stabilized (due to resonance) than in other simpler aliphatic aldehydes. I'd like to add that steric factor is equally responsible for its low reactivity at the carbonyl group.
