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. Provide the IUPAC name for the following alkene:
CH₂=CH-CH₂-CH₃
2. Name the following compound:
CH₃-CH=CH-CH₃
3. The longest continuous carbon chain containing the double bond is called the . The numbering of the parent chain should start from the end closer to the .
4. When naming alkenes, the suffix is used to indicate the presence of a carbon-carbon double bond.
5. Which of the following is the correct IUPAC name for an alkene with five carbon atoms and a double bond between the first and second carbon atoms?
Pent-1-ene
1-Pentene
Pentene
Pent-2-ene
6. Draw the condensed structural formula for 3-methylbut-1-ene.
7. Draw the condensed structural formula for 2,3-dimethylbut-2-ene.
8. The IUPAC name for CH₂=CH-CH(CH₃)-CH₃ is 3-methylbut-1-ene.
