9.3 Naming aldehydes and Ketones Aldehydes are named by replacing the terminal -e of the corresponding alkane name with -al The parent chain must contain the -CHO group, the--CHO carbon is numbered as c(1) If the-CHO group is attached to a ring, use the suffix for common names
9.3 Naming Aldehydes and Ketones • Aldehydes are named by replacing the terminal -e of the corresponding alkane name with –al • The parent chain must contain the ¾CHO group, the ¾CHO carbon is numbered as C(1) • If the ¾CHO group is attached to a ring, use the suffix for common names
Naming Ketones Replace the terminal -e of the alkane name with -one Parent chain is the longest one that contains the ketone group Numbering begins at the end nearer the carbonyl carbon
Naming Ketones • Replace the terminal -e of the alkane name with –one • Parent chain is the longest one that contains the ketone group –Numbering begins at the end nearer the carbonyl carbon
