Aromatic hydrocarbons
Alkenes and alkynes are two families of organic molecules that contain multiple____.
Bonds
These are compounds that contain a carbon-carbon double bond.
Alkenes
What is the molecular formula for alkenes?
CnH2n
These are compounds that contain a carbon-carbon triple bond.
Alkynes
What is the molecular formula for alkynes?
CnH2n-2
Alkenes and alkynes have ____ melting and boiling points, _____ in water and _____ hydrocarbons.

These are compounds that co rain fewer than the maximum number of hydrogen atoms per carbon.
Unsaturated hydrocarbons
List the steps in naming alkenes and alkynes.
- Find the longest chain that contain both carbon atoms of the double or triple bond.
- Number the carbon chains from the end closest to the bond.
- Number and name the substituents and write their name.
Compounds with two double
Bonds are called ____ and each double bond gets its own number.
Dienes
This is three constitutional isomers for an alkene of the same molecular formula.
Cis-Trans isomers

Cis
When the two CH3 groups are on opposite sides of the double bond the compound is called the _____ isomer. And is named as such in the prefix.
Trans
