Alkenes are hydrocarbons that contain at least one carbon-carbon double bond, giving them a trigonal planar molecular geometry and 120 degree bond angles. Common alkenes like ethene and propene were discussed as examples, with ethene having two carbons and propene having three carbons in its double bond. Alkenes are important starting materials that are used to make products like alcohols, plastics, detergents, and fuel due to the reactivity of their semi-movable carbon-carbon double bonds.

1. Alkene
By: Alex Peterson

2. Alkene
Definition:
- A saturated Hydrocarbon that has one at
least carbon-carbon double bond
-The molecular geometry is trigonal planar
- The bond angle is 120
-Slight Rotation

3. Ethene
• Ethene is 2 carbon double
bond with 4 hydrogens around
it

4. Propene
- Is a 3 carbon bond with 6
surrounding hydrogens
-The double bond is
between 1 and 2

5. Fun Fact
Alkenes are used as starting
materials for alcohols,
plastics, detergents, and
fuel

6. Conclusion
• The most important thing I learned about
alkenes was the carbon carbon double bond,
and that there semi moveable bonds can make
them be used from plastic to fuel.
