Aldehydes and Ketones I. Nucleophilic Addition to the Carbonyl Group

Aldehydes and Ketones I. Nucleophilic Addition to the Carbonyl Group

Aldehydes and Ketones I. Nucleophilic Addition to the Carbonyl Group. Chapter 16. Except for formaldehyde, all aldehydes have a carbonyl group bonded on one side to a carbon and on the other side to a hydrogen. In ketones , the carbonyl group is situated between two carbon atoms.
