Nomenclature of ketones

Common names use the names of the R (alkyl groups) or Ar (Arene group) as separate words, along with word ketone.

The structure and 2-ethyl-4-methylpentanal nomenclature of some aldehydes and ketones. 

Functional modifiers are used in binary nomenclature to name anhydrides, e.g. acetic anhydride for (CH3-C0)20, and derivatives of ketones and aldehydes such as oximes, hydrazones and semicarbazones, e.g. acetone oxime for (CH3)2C=NOH. 

The carbonyl group, C=0, is present in both aldehydes (RCH=0) and ketones (R2C=0). The IUPAC ending for naming aldehydes is -a/, and numbering begins with the carbonyl carbon. The ending for the names of ketones is -one, and the longest chain is numbered as usual. Common names are also widely used. Nomenclature is outlined in Sec. 9.1. 

The IUPAC rules for naming ketones append the suffix -one to the parent name. The position of the ketone carbon is indicated by a locant number. Figure 11.37 gives three nomenclature examples of ketones. The simplest ketone, propanone, is commonly known as acetone. Acetone is an excellent solvent for most organic compounds and is the main ingredient in fingernail polish remover. Acetone is one of the ketone bodies that build up in the bloodstream from excessive metabolism of fats. Because ketones typically have a sweet taste and odor, this can give a patient with ketosis a characteristic acetone breath. ... 

A word about nomenclature. Once upon a time, chemists made a useful distinction between acetals (derived from aldehydes) and ketals (derived from ketones) which has since perished. The International Union of Pure and Applied Chemistry (IUPAC) decided (Rule C-331.1) that the term ketal is redundant and that the term acetal should now apply to all 1,1-to-ethers whether derived from aldehydes or ketones. Nevertheless, in A Guide to IUPAC Nomenclature of Organic Compounds, Recommendations 1993 (R. Panico, W.H. Powel, I-C Richter, Eds. Blackwell Science Oxford, 1993) the IUPAC graciously reinstated the term ketal , by popular demand, as a subclass of the generic term acetals (Rule R-5.6,4),... 

Both D- and L-forms of the ketohexose related equally to altrose and allose are known. In conformity with the present system of nomenclature for ketone sugars, the name allulose is used in preference to the older terms pseudofriictose, psicose, 2-ketoribohexose, etc.
