Read each question carefully and provide the correct IUPAC name for the given alkene structures, or draw the structure from the given name. Pay attention to stereochemistry (E/Z) where applicable.
1. The IUPAC name for CH2=CH-CH3 is .
2. In alkene nomenclature, the longest continuous carbon chain containing the double bond is called the chain.
3. When assigning numbers to the carbons in an alkene, the double bond should receive the possible numbers.
1. Give the IUPAC name for the following compound:
2. Draw the condensed structural formula for (E)-3,4-dimethyl-2-pentene.
1. Which of the following compounds exhibits E/Z isomerism?
Ethene
Propene
2-Butene
2-Methylpropene
2. What is the correct IUPAC name for the following alkene?
2-Methyl-2-butene
3-Methyl-2-butene
2,3-Dimethyl-2-propene
2-Methyl-3-butene
1. All alkenes can exhibit E/Z isomerism.
True
False
2. The 'Z' configuration in E/Z isomerism indicates that the higher priority groups are on opposite sides of the double bond.
True
False
Match the alkene with its correct IUPAC name.
1. CH2=CH2
a. 1-Butene
2. CH3-CH=CH-CH3
b. Ethene
3. CH2=CH-CH2-CH3
c. 2-Butene
