- Draw all the isomers of C,H0. Clearly show stereochemistry if stereoisomers are possible. Step 1: Start by drawing all the isomers with double bonds. • Consider constitutional isomers, then stereoisomers. Step 2: Draw all isomers containing a ring. • Consider constitutional isomers, then stereoisomers. The longest chain does not have to contain all five carbon atoms. Draw the alkene isomers that have a 4-carbon main chain.arrow_forwardWhich alkene is required to complete the reaction in Figure 10? * A B C D All of these alkenes will form this alcohol.arrow_forward4.
