Alkenes & Alkynes

Changes in the structure of the carbon chain can completely change the chemistry of the molecule

• True

• False

ALKANES are...

• Unsaturated hydrocarbons

• Saturated hydrocarbons

• Polycarbons

• Monocarbons

ALKENES have

• Only single bonds

• At least one double bond

• All double bonds

• At least one triple bond

ALKYNES are unsaturated hydrocarbons that have at least one triple bond.

• True

• False

What isomer is the molecule in the left.

• Cis isomer

• Trans isomer

What isomer is the molecule on the bottom.

• Cis isomer

• Trans isomer

• Cis and Trans Isomers

• Alanes and Alkynes

• Double or triple bonds

• Saturated and Unsturated hydrocarbons

Alkenes usually go through addition reactions because....

• they are hydrocarbons

• they are saturated

• they can't form isomers

• they have double bonds
