Compounds where the ring structure is made purely of carbon atoms.

Carbocyclic compounds that resemble aliphatic compounds and contain a ring of 3 or more carbon atoms.

Carbocyclic compounds containing a benzene ring (six carbon atoms with alternating double and single bonds).

Compounds with a ring structure containing carbon and at least one other element (like nitrogen, oxygen, or sulfur).

The non-carbon atom in a heterocyclic compound.

An atom or group of atoms that determines the chemical properties of an organic compound.

Alicyclic hydrocarbons where each carbon atom has four single bonds.

CnH2n

Organic compounds that contain only carbon and hydrogen atoms.

The ability of carbon atoms to form long chains by bonding to each other.

Hydrocarbons where all carbon atoms have four single bonds and cannot hold any more hydrogen atoms.

Hydrocarbons with at least one double or triple bond between carbon atoms.

Unsaturated hydrocarbons with one or more double bonds between carbon atoms.

A measure of a fuel's resistance to knocking (premature combustion) in an engine. Higher octane numbers indicate better resistance.

A branched-chain hydrocarbon (2,2,4-trimethylpentane) used as a reference standard for octane ratings. It has an octane number of 100.

A process used to improve the octane number of gasoline by converting straight-chain hydrocarbons into branched-chain hydrocarbons.

An antiknock agent that used to be added to gasoline to improve its octane number, but is no longer used due to its harmful environmental impacts.

Organic compounds with an open chain of carbon atoms. These chains can be straight or branched.

Cyclic compounds where the ring is only made up of carbon atoms.
