Alkenes 14.1 - 14.3

Unsaturated --> contains at least one carbon-carbon double bond 

Bonding in alkenes, a hybrid orbital form each carbon overlaps to form a double bond 

Alkenes 

• Double bond is not just two single bonds. 
• One of the pairs of electrons is held between the two carbons but the other is in a molecular orbital above  and below the plane of the molecule.
• Single bonds are referred to as sigma bonds.
• The second bond in a double bond is called pi bond.
• Electrons in the pi bond can move anywhere within the orbital. Alkanes have an area of high electron density.

Monomer -->small molecule that combines with many other monomers…
