Question

As mentioned in the chapter opener, oil from the kukui nut contains linolenic acid. Hi Solu HH C=C CH2CH2CH =Ć C CH CHÚCH CH-CH=CH-CH-CH-COOH Guided linolenic acid (a) When linolenic acid is partially hydrogenated with one equivalent of H, in the presence of a Pd catalyst, three constitutional isomers are formed. One of them is linoleic acid. Draw the structure of one of the other two possible products. draw structure ... (b) What product is formed when linolenic acid is completely hydrogenated with three equivalents of H2?
