cycloalkane
Let an agent explain cycloalkanes, relay structure, nomenclature, conformations, properties and uses from organic chemistry and safety sources, describe the named compounds, relay fire safety, and distinguish cycloalkanes from alkanes, cycloalkenes, aromatic compounds and heterocycles.
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 cycloalkanes, relay structure, nomenclature, conformations, properties and uses from organic chemistry and safety sources, describe the named compounds, relay fire safety, and distinguish cycloalkanes from alkanes, cycloalkenes, aromatic compounds and heterocycles.
A saturated hydrocarbon containing one or more rings of carbon atoms with the general formula CnH2n for monocyclic compounds, including cyclopropane and cyclobutane, whose ring strain makes them reactive, cyclopentane and cyclohexane, which adopts a strain-free chair conformation, substituted forms the registry aliases name such as methylcyclopentane, ethylcyclohexane and 1,1-dimethylcyclohexane, and large rings such as cyclododecane and cyclohexadecane; cycloalkanes, also called naphthenes, occur in petroleum and are used as solvents and chemical feedstocks, notably cyclohexane for nylon production. Many are flammable and should be handled with fire safety precautions.
What it is for: Solvents, fuels and chemical feedstocks.
It can be explain structure and nomenclature; relay conformations and properties; describe named compounds; relay fire safety.
Distinguishing features
Carbon rings
Saturated
Ring strain varies
Conformations
What it looks like
Mostly colourless liquids with a mild odour; larger rings are waxy solids.
Physical character
general formula: CnH2n formula - monocyclic
cyclohexane boiling point: about 80.7 degrees Celsius
Baeyer strain theory: 1885 year - Adolf von Baeyer
How it is recognised
Saturated ring hydrocarbon
Cyclododecane, cyclohexadecane, ethylcyclohexane, cyclohexane, 1,1-dimethylcyclohexane, methylcyclopentane
Alkanes are open chains; cycloalkenes have double bonds; aromatics such as benzene have delocalised rings; heterocycles contain non-carbon ring atoms
