Read each question carefully and provide the correct IUPAC name for the given alkene structures or draw the structure from the given name. Remember to indicate the position of the double bond and any substituents.
1. Alkenes are hydrocarbons that contain at least one Carbon-Carbon bond.
2. The suffix used for naming alkenes is .
3. When numbering the carbon chain in an alkene, the double bond should receive the possible number.
1. What is the correct IUPAC name for the following compound?
But-2-ene
1-Butene
2-Butene
Butene
2. Which of the following is the parent chain for 3-methylpent-1-ene?
Butane
Pentene
Hexene
Propene
1. Draw the condensed structural formula for 2,3-dimethylbut-2-ene.
