2-Butene

2. What is the parent chain for the following alkene: CH₃-CH=C(CH₃)-CH₂-CH₃?

Pentane

Hexane

Pent-2-ene

Hex-2-ene

3. The suffix used for naming alkenes is .

4. In E/Z isomerism, the Z configuration indicates that the higher-priority groups are on the side of the double bond.

5. Draw the condensed structural formula for (E)-3,4-dimethylhex-2-ene.

6. Give the IUPAC name for the following compound, including any E/Z designation:
