Types of Aliphatic Hydrocarbons Quiz

Organic Compounds

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

Separation of Hydrocarbons

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

Aliphatic Hydrocarbons

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

Cycloalkanes, Cycloalkenes, and Cycloalkynes

• 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

• 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.

Origin of the Term 'Aromatic'

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