Carbonyl electrophilicity
WebJul 20, 2024 · The s and p bonds between the carbon and oxygen combine to make the C = O double bond that defines the carbonyl functionality. Nucleophilic addition The carbon-oxygen double bond is polar: oxygen is more electronegative than carbon, so electron density is higher on the oxygen end of the bond and lower on the carbon end.
