In the acid-catalyzed nucleophilic addition mechanism, what is the specific role of the proton (H+) in relation to the carbonyl carbon's reactivity?
Q1. In the acid-catalyzed nucleophilic addition mechanism, what is the specific role of the proton (H+) in relation to the carbonyl carbon's reactivity?
Answer: Increase carbon's electrophilic character
Explanation: In acid-catalyzed addition, protonation of oxygen increases the electrophilicity of the carbonyl carbon, allowing even weak nucleophiles to attack efficiently.
