Alkenes and Alkynes

- hydrocarbons that contain one or more double bonds
- Non-polar
- General formula CnH2n

- Unsaturated hydrocarbon
- Boiling points are slightly less than the boiling points of similar-sized alkanes
- Non-polar – low solubility in water
- More reactive than alkanes

- Follow the same format as alkanes:
Prefix+Root+ Suffix

*the suffix for alkenes is -ene

- Also need the location of the double bond
- The double bond has the lowest possible position number

- Each carbon in the C=C double bond must be attached to two different groups.
- In a cis isomer the two larger groups are attached to each C=C double bond on the same side.
- In a trans isomer, the two larger groups are attached to each C=C double bond on opposite sides.

- Contain one or more triple bonds
- Unsaturated hydrocarbons
- Structure with a triple bond is linear
- More reactive than the double bond
- General formula CnH2n-2
- Naming alkynes follow the same rules for alkenes
