  2. Nomenclature of Aldehydes: IUPAC Aldehydes 1. Find the longest chain to contain CHO group; this is the parent chain. 2. This parent chain’s name ends in ‘al’ - the suffix. E.g., take alkane and convert to alkanal. 3. Number the parent chain such that the C=O carbon gets the #1 designation. 4. Give name; be sure to list substituents alphabetically and to give their location; these are the prefixes. Remember that sec-, tert-, o-, m-, p-, di-, tri-, tetra- are not considered when alphabetizing, but iso is. Name the following:

  3. Nomenclature of Ketones: IUPAC B. Ketones 1. The parent chain contains the C=O carbon; this is the parent chain. 2. This parent chain’s name ends in ‘one’ - the suffix. E.g., take alkane and convert to alkanone. 3. Number the parent chain such that the C=O carbon gets the lowest # possible. 4. When naming, give the location of the C=O carbon in the parent name. 5. Give name; be sure to list the parent chain substituents alphabetically and to give their location; these are the prefixes. Remember that sec-, tert-, o-, m-, p-, di-, tri-, tetra- are not considered when alphabetizing, but iso is. Name the following:
