1. Draw the cis and trans isomers of: a) 3-octene b) 4-ethyl-3-methyl-3-octene 2. Draw the structures of the following 5-carbon molecules. Which are isomers of each other? Explain the types of isomerism involved: a) pentanal b) 2-pentanone c) 3-pentanone d) 1-pentanol e) 2-pentanol f) cyclopentanol 3. Draw the structural formula for 3-methylhexane and 2-pentanol. In each of these molecules, identify the chiral carbon and the four "groups" attached to the chiral carbon.
