Chapter 23.2, Problem 3CYU

There are 17 possible alkene isomers with the formula C₆H₁₂. Draw structures of the five isomers in which the longest chain has six carbon atoms, and give the name of each. Are any of these isomers chiral? (There are also eight isomers in which the longest chain has five carbon atoms, and four isomers in which the longest chain has four carbon atoms. How many can you find?)
