Draw a structural formula for the substitution product of the reaction shown below. H3C CI CH3OH • Use the wedge/hash bond tools to indicate stereochemistry where it exists. • If more than one stereoisomer of product is formed, draw both. • Separate multiple products using the + sign from the drop-down menu.

There can be more than one correct answer.
3. Draw the structural formula of 3-bromo-2-chloropentane. Identify the chiral carbons with asterisks. Using 2n formula (n is number of chiral centers) calculate the number of stereoisomers. Construct 2 pairs of mirror images. Take one pair of the enantiomers, compare it with the either of the models of the second pair of enantiomers. Are these two molecules mirror images? Draw the fisher projections of the four stereoisomers and identify diastereomers.

References H3C H3C CH3 CH3 CH3 Br DMSO (solvent) CH3 Functional groups such as alkynes react the same in complex molecules as they do in simpler structures. Draw the expected product(s) for this reaction. • Use the wedge/hash bond tools to indicate stereochemistry where it exists. • If the reaction produces a racemic mixture, draw both stereoisomers. Separate structures with + signs from the drop-down menu. • Should you want to restart the exercise, the drop-down menu labeled= starting points = can be used to redraw the starting molecule on the sketcher.

For the molecule below, 1. Indicate whether or not it has a stereoisomer (type yes or no in Blank #1). 2. If your answer to 1. is yes, identify the type of stereoisomer in Blank #2 (choose from enantiomer or geometric - watch your spelling!). If your answer to 1. is no, type none in Blank #2.
