PowerPoint about Alkenes

1. Alkenes-Ethene and
Propene
By: Rebekah Burke

2. Alkenes
Alkenes are unsaturated hydrocarbons that have at least
one carbon double bond
Alkenes have a trigonal planar molecular shape
around the carbons with a double bond
Alkenes have a bond angle of 120 degrees and they do
not rotate freely like alkanes

3. Ethene
C2H4
-has one double bond
-colorless flammable gas
- simplest alkene

4. Propene
C3H6
- also known as propylene or methyl ethylene
-has one double bond

5. What are Alkenes found in?
Alkenes form monomers and then join together to form polymers to
make plastic. Polymers are made by the double bonds in the alkene
breaking open.

6. Alkenes also known as olefins have a
double bond, a trigonal planar shape,
and a bond angle of 120. Ethylene and
Propylene are the simplest alkenes.
