2a. Draw the dash-wedge structures and Fischer projections of the following molecules. R-1-bromoethanol (2S, 3R) -...
Give the structures using both the dash-and-wedge (3D or perspective) formula and Fischer projections for each of the following compounds. a) (3S,4R)-3-bromo-4-methylhexane b) (2R,3R,4S,5S)-2,4-dibromo-5-chloro-3-methylhexane
(a) Draw the saw-horse (or wedge-dash) projection of (2S,3R)-3-methylpentan-2-ol. [Marks: 1] (b) Draw the Newman projections of the 2-3 bond in (2S,3R)-3-methylpentan-2-ol. [Marks: 2] (c) Based on the Newman projections from part b. - draw a rotation vs. energy diagram (you do NOT need to give specific energy values in this diagram) that will allow you to identify the most stable confirmation around the 2-3 bond. Assume the greatest steric and torsional strain occurs when the hydroxyl and ethyl groups...
