> See also: > - [[Naming Hydrocarbons (IUPAC)]] # Hydrocarbons | Type | Involve | Descriptions | | --- | --- | --- | | **Alkanes** | Single ($\sigma$) Bonds | No $\pi$ bonds present (A saturated hydrocarbon) | | **Alkenes** | | | | **Alkynes** | | | - **Alkanes:** No $\pi$ bonds present (A saturated hydrocarbon) - Cycloalkanes ($C_nH_{2n}$) - **Alkenes:** Contain two adjacent carbon double bonds - terminal vs interior alkenes - **Alkynes:** Contain a carbon-carbon triple bond - terminal vs interior alkynes > If a molecule is described as "lacking a $\pi$ bond, it is a single bond." > [!info] Saturated vs Unsaturated Hydrocarbons > **Alkanes** are considered to be fully **saturated** with hydrogen atoms. > > Alkenes and Alkynes are considered "**unsaturated**" as they do not have the **maximum amount of hydrogens possible** within the molecule (instead having $\pi$ bonds within the carbon atoms). ## Properties of Hydrocarbons There is a reason C-H bonds are so cool Alkyl Groups - Alkyl Halides ( ) ## Hydrocarbon Reactions There are many reaction classifications involving alkanes, alkenes, and alkynes that... - [[Alkene Reactions]] - [[Alkyne Reactions]] - [[Radical Reactions]]
