hydrocarbon
Let an agent explain hydrocarbons and their classes, relay properties, sources and uses from chemistry references, describe their role as fuels and feedstocks, and distinguish hydrocarbons from other organic compounds, from petroleum as a mixture and from carbohydrates.
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 hydrocarbons and their classes, relay properties, sources and uses from chemistry references, describe their role as fuels and feedstocks, and distinguish hydrocarbons from other organic compounds, from petroleum as a mixture and from carbohydrates.
An organic compound consisting entirely of hydrogen and carbon, from methane and the alkanes through alkenes, alkynes and aromatic compounds such as benzene to large polymers, forming the main constituents of natural gas, petroleum and coal-derived fuels and the feedstock of the petrochemical industry; hydrocarbons are classified by bonding and structure and are studied in organic chemistry.
What it is for: Not applicable; a class of compounds.
It can be explain classes; relay properties and uses; describe environmental aspects; distinguish related concepts.
Distinguishing features
Carbon and hydrogen only
Classified by bonding
Fuel and feedstock
Nonpolar
What it looks like
Gases, liquids or waxy solids, mostly colourless.
Physical character
simplest: methane, CH4 note
boiling points: rise with chain length note
combustion products: carbon dioxide and water note - complete
How it is recognised
Compound of carbon and hydrogen only
Alkanes, alkenes, alkynes, aromatics, polymers such as polyethylene
Other organic compounds contain heteroatoms; petroleum is a mixture; carbohydrates contain oxygen
