CHM2210 003 Fall 2017 E2 WR (Chapters 4-5) Practice exam-like format 1. Draw one of the possible diastereoisomers for the following molecule / 1 pts 2. Assign the configuration for each chiral center in the following molecule, and draw its /3 pts enantiomer OH 3. Draw the Newman projection of the following molecule. The arrow points to the front carbon. Use the circle drawn to complete the Newman projection. ol /1 pts Br Br Cl /2 pts

Answer 1

Enantiomers means mirror images of each other and diasteroisomers means hot mirror images of each other It is easy that draw the enantiomer of this compound Then any other compound you draw can compare with enantiomer If it is not like enantiomer your answer would be correct Your answer is correct It is not like like enantiomer \r\n View the molecule along the C_2 - C_3 axis with your eye closest to C_2 Wedges go on left hand side dashes go on right hand side Your answer is correct \r\n Rules for assigning an R/S designation to a chiral center 1: Assign priorities to the four substituents , with # 1 being the highest priority and #4 the lowest priorities are based on the atomic number 2: Trace a circle from #1 to #2 to #3 3: Determine the orientation of the #4 priority group . If it is oriented into the plane of the page
