alcohols
Let an agent explain alcohols as a chemical class and their properties and reactions, describe uses and toxicity, distinguish ethanol in beverages from other alcohols, and support learning in chemistry.
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 alcohols as a chemical class and their properties and reactions, describe uses and toxicity, distinguish ethanol in beverages from other alcohols, and support learning in chemistry.
A class of organic compounds containing one or more hydroxyl groups bonded to a saturated carbon atom, including methanol, ethanol, propanol and higher alcohols, diols and polyols such as ethylene glycol and glycerol, and classified as primary, secondary or tertiary by the carbon bearing the hydroxyl; alcohols are solvents, fuels, feedstocks and intermediates, ethanol is the alcohol in alcoholic beverages, and methanol and other alcohols are toxic.
What it is for: Organic compounds with hydroxyl groups.
It can be explain the class and reactions; describe uses and toxicity; distinguish ethanol from other alcohols; support learning.
Distinguishing features
Hydroxyl group
Hydrogen bonding
Primary, secondary, tertiary
Varied toxicity
What it looks like
Usually clear liquids; higher alcohols may be waxy solids.
How it is recognised
Hydroxyl group on saturated carbon
Methanol, ethanol, propanol and others
Phenols have hydroxyl on an aromatic ring; ethers have no hydroxyl
