Linoleic acid (below) is an essential fatty acid found in many vegetable oils, such as soy, peanut, and cottonseed. a key structural feature of the molecule is the cis orientation around its two double bonds, where r1 and r2 represent two different groups that form the rest of the molecule. (a) how many different compounds are possible, changing only the cis/trans arrangements around these two double bonds? (b) how many are possible for a similar compound with three double bonds?
