My Flashcards

Definition

Meaning

A saturated hydrocarbon with the chemical formula C₁₀H₂₂, consisting of a chain of ten carbon atoms.

Any of the isomeric forms of this alkane, used as a reference in organic chemistry and as a component in fuels and solvents.

Linguistics

Semantic Notes

The term is part of the systematic nomenclature for alkanes (methane, ethane, propane...). It refers specifically to the straight-chain isomer (n-decane) unless otherwise specified. It is a colorless liquid at room temperature.

Memory Aids

Mnemonic

Think 'DEC-ane' for its TEN (like in decade) carbon atoms.

Conceptual Metaphor

N/A (Highly technical term with little metaphorical extension).

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Do not confuse with 'декан' (dean of a university faculty). The chemical term is 'декан' in Russian, but the context makes the meaning clear.

Common Mistakes

  • Mispronouncing it as /dɪˈkeɪn/ (like 'decade').
  • Using it in general conversation where 'fuel' or 'chemical' would be more appropriate.
  • Confusing it with other alkanes like 'octane' or 'dodecane'.

FAQ

Frequently Asked Questions

Like many hydrocarbons, it is flammable and its vapours can be harmful if inhaled in large quantities. It should be handled with standard laboratory safety precautions.

It is primarily used as a solvent, a component in fuels, and a standard reference compound in chemical analysis and research.

Gasoline is a complex mixture of many different hydrocarbons, including some decane. Decane is a single, specific chemical compound.

Not as a pure substance. You might encounter it as a minor component in products like lighter fluid, certain solvents, or jet fuel, but it is not a household name.
