Nomenclature of Aldehydis The longest chain carrying the - CHO group is allected . The corresponding word root and the primary suffix l-ane, - one or yne i generally the final é is dropped ) This is followed by attaching the suffix '- al' to designate the aldehyde group. The position of substituents if any, are indicated by suitable numbers, the aldehydic carbon always getting the number 1 because it is a chain terminating group. For this reason , the number of the aldehydic carbon is not usually mentioned Kelones IUPAL name of Ketones carry the suffix given according to the usual rules. '-one and are The longest chain containing the carbonyl group is selected from the wrresponding hydrocarbon, the suffix 'e' us replaced by one. The carbon of the Kilonic group is assigned the minimum possible number along the straight chain g varbon atoms and the substituent groups carry other suitable nun numbers.
