- Although fresh human sweat has no odor, enzymes in skin bacteria form a variety of compounds with distinctive, pungent odors. The two enantiomers of 3-methyl-3-sulfanyl-1-hexanol (A), which smell somewhat differently, contribute to the characteristic foul odor of sweat. Locate the chirality center in A and draw both enantiomersarrow_forwardCalculate the number of degrees of unsaturation for each molecular formula:(a) C5H8O; (b) C6H11Cl; (c) C8H9N. Propose one possible structure for eachcompound.arrow_forwardGiven the following structure and numbering: (a) Label the stereocenters of A as R or S and draw a Fischer Projection of the enantiomer of A with C1on top and C4 on bottom. (b) Draw a Newman Projection of a diastereomer of A looking down the C2-C3 bond with C2 in front.arrow_forward
- Consider the below structure: a. Draw 3-D structures and a Fischer projection for the 1R, 2S, and the 1S, 2S stereoisomers of the above structure. b. Draw all the conformers obtained by rotation about the C1-C2 bond and rank them in order of increasing stability.arrow_forwardThe following compound has only one asymmetric center. Why then does it have four stereoisomers?
