The term “hydrocarbon” refers to compounds that contain only carbons and hydrogens. 

Hydrocarbon Classifications

Concept #1: Identifying Types of Hydrocarbons

Hydrocarbons not found in rings are commonly called aliphatic hydrocarbons, while those in rings are commonly referred to as cyclic hydrocarbons. 

Alkane Prefixes

Concept #2: Learning the different alkane prefixes

The name of alkanes is based on the number of carbons in the compound and each has a set alkane prefix. 

Alkanes

Concept #3: Understanding Alkanes

Alkanes are hydrocarbons that contain only single bonds. They are sometimes referred to simply as “ saturated” hydrocarbons.

Example #1: Determine the formula and name of a hydrocarbon that contains only single bonds and 8 carbons. 

Alkenes

Concept #4: Understanding Alkenes

Alkenes are hydrocarbons that contain at least one double bond. They are sometimes referred to simply as “unsaturated” hydrocarbons.

Example #2: Determine the formula and simplest name of a hydrocarbon that contains one double bond and 6 carbons. 

Alkynes

Concept #5: Understanding Alkynes

Alkynes are hydrocarbons that contain at least one triple bond. They are sometimes referred to simply as “unsaturated” hydrocarbons just like the alkenes. 

Example #3: Determine the formula and simplest name of a hydrocarbon that contains one triple bond and 9 carbons. 

Aromatic Hydrocarbons

Concept #6: Understanding Aromatic Hydrocarbons

Aromatic compounds have a benzene ring (C6H6) as their major defining feature.
