Unformatted text preview: Chapter 19: Aldehydes and Ketones: Nucleophilic Addition Reactions General Structures: Aldehydes Ketones Characterized by the presence of a carbonyl functional group Carefully read over the carbonyl compound preview found on pages 686694 (Mandatory) Title: Page %d of %d Aldehydes: Nomenclature Replace the e ending of the corresponding alkane name with al Ex. Methane becomes Methanal The parent chain must contain the CHO group and the carbonyl's carbon atom is labeled as carbon 1 For more complex aldehyde compounds (CHO group attached to a ring), the suffix carbaldehyde should be used Examples: Title: Page %d of %d Aldehyde Common Names Title: Page %d of %d Ketones: Nomenclature Replace the e ending of the corresponding alkane name with one Ex. Hexane becomes hexanone The parent chain must contain the carbonyl group and the carbonyl's carbon atom is given the lowest number possible on the chain When the RC=O group is used as a substituent, it is referred to as an acyl group and the ending yl is attached to its root carboxylic acid name When other groups are present and the carbonyl group is considered a substituent on a parent chain, the prefix oxo is used to identify the ketones position Title: Page %d of %d Examples: Title: Page %d of %d Aldehyde and Ketone Preparation Aldehyde Synthesis: (Review) Oxidation of 1 oalcohols Oxidative cleavage of alkenes Carboxylic acid derivatives can be partially reduced to form aldehydes Title: Page %d of %d Aldehyde and Ketone Preparation...
