Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain ketones and their chemistry, relay nomenclature, properties, reactions and uses from organic chemistry references, describe biological ketones and ketone bodies in general terms, and distinguish ketones from aldehydes, esters, enones and the dietary sense of ketosis.

An organic compound containing a carbonyl group bonded to two carbon atoms, with the general formula R-CO-R, from acetone, the simplest and most common, through industrial solvents such as methyl ethyl ketone to sugars such as fructose, steroid hormones and the ketone bodies produced in fasting; ketones are named with the suffix -one, are less reactive than aldehydes and are widely used as solvents and synthetic intermediates.

What it is for: Not applicable; a class of compounds.

It can be explain structure and nomenclature; relay reactions and uses; describe biological roles; distinguish related classes.

Distinguishing features

Carbonyl group

Two carbon substituents

Solvent use

Biological members

What it looks like

Not a visible object; often colourless liquids with a characteristic odour.

Physical character

general formula: R-CO-R structure

acetone boiling point: 56 C

acetone production: about 7 million tonnes per year - estimates

How it is recognised

Carbonyl between two carbons

Acetone, methyl ethyl ketone, cyclohexanone, fructose, ketone bodies

Aldehydes have a hydrogen on the carbonyl; esters have an oxygen; enones are conjugated ketones
