Practice Problem 6

Name the following compound.

Solution

This compound is a derivative of hexane because the longest carbon chain contains six carbon atoms. It contains a C=C double bond, which means it is a hexene. Because the double bond links the second and third carbon atoms, it is a 2-hexene. Because the CH₃ substituents are on the third and fifth carbon atom, the compound is 3,5-dimethyl-2-hexene.
