Study Notes

The simplest organic compounds are composed of hydrocarbons, which are made up of only hydrogen and carbon atoms.

Hydrocarbons can be separated through fractional distillation, which takes advantage of differences in boiling points.

There are three types of aliphatic hydrocarbons: alkanes, alkenes, and alkynes, which differ in the types of bonds between carbon atoms.

Cycloalkanes are saturated cyclic hydrocarbons, cycloalkenes are unsaturated cyclic hydrocarbons with one or more carbon-carbon double bonds, and cycloalkynes are unsaturated cyclic hydrocarbons with one or more carbon-carbon triple bonds.

Benzene, a unique hydrocarbon, has a planar, ring-shaped structure, which gives it physical and chemical properties that are markedly different from alkanes.
The planar, ring-shaped structure of benzene is due to the delocalization of electrons in the ring.

The term 'aromatic' was originally used to describe this class of compounds because many of them have a sweet, pleasant odor.
