- (A)Menthol, used to flavor various foods and tobacco, is the most stable stereoisomer of 2-isopropyl-5-methylcyclohexanol. Draw its most stable conformation. Is the hydroxyl group cis or trans to the isopropyl group? To the methyl group? (b) Neomenthol is a stereoisomer of menthol. That is, it has the same constitution but differs in the arrangement of its atoms in space. Neomenthol is the second most stable stereoisomer of 2-isopropyl-5methylcyclohexanol; it is less stable than menthol but more stable than any other stereoisomer. Write the structure of neomenthol in its most stable conformation.arrow_forwardWhat is the major organic product of the following reaction? (a) (b) NaBH4 CH3CH₂OH ?

Since humans cannot synthesize fats with double bonds past carbon #9, it is "essential" and must be obtained from the diet. Hope you like salmon! If a serving of salmon contains 500.0 mg of ALA and all of it is completely oxidized via B-oxidation and the TCA, how many grams of water at room temperature can be brought to a boil using that energy?
