2 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:

5 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
