Stereochemistry Chapter
Please draw two structures (1 structure with the 4th group as wedge/dashed bond, 2nd structure where the 4th group is not wedged or dashed) Please also identify R or S configuration for each. Be sure to include the rank of the substituents.

You must show the ranking of substituents to get credit!!! (8 points). NH2 13. Draw the perspective formula of the following molecule (dashed wedge structure) and its mirror image (2 points). Denote each enantiomer as being Rom S. You must show the ranking of substituents to get credit!!! (8 points). 3-chlorohexane
1) Predict the Products: Using line drawings with proper use of
dashed wedge and solid wedge notation where necessary, draw the
major organic products of the following reactions in the boxes
provided. If no reaction occurs write “no reaction” or “N.R.” in
the box. Include stereochemistry in your answers where appropriate.
If a product is racemic draw both enantiomers or write “racemic”
next to the structure. Assume all reagents written above and below
the arrows are present in excess unless...
