WebSolution: CH3 CH3 3.55 There are four cis-trans isomers of menthol, including the one shown. Draw the other three. Answer: CH3 OH OH CH (CH3)2 CH (CH3)2 CH3 CH3 CH (CH3)2 CH (CH3)2 CH3 OH OH 3.56 Malic acid, C4H6O5, has been isolated from apples. Natural menthol exists as one pure stereoisomer, nearly always the (1R,2S,5R) form (bottom left corner of the diagram below). The eight possible stereoisomers are: In the natural compound, the isopropyl group is in the trans orientation to both the methyl and hydroxyl groups. Thus, it can be drawn in any of the ways shown:

WebOct 19, 2024 · The way I was taught to find stereoisomers was to count the number of double bonds that can be E / Z and the stereocentres, and do 2 n. There are no stereocentres, and no double bonds, so the number of stereoisomers would only be 1 (only one molecule). This disagrees with the cis -/ trans -isomers number which would be 2. http://employees.oneonta.edu/knauerbr/226hw_ans/226hw2ans.pdf oriental trading peanuts halloween
