Based strictly on electronic and steric factors, which of the following carbonyl compounds is the LE — Aldehydes Ketones and Carboxylic Acids Chemistry Question

💡 Solution & Explanation

Benzophenone is the least reactive. Sterically, it has two massive, bulky phenyl rings hindering the approach of the nucleophile. Electronically, the positive charge on the carbonyl carbon is strongly stabilized by the +R (resonance) effect of both phenyl rings, heavily reducing its electrophilicity.
