5. Instead of redrawing the molecule to make the lowest priority group point back, alternatively, the lowest priority group can be swapped with the group that is currently pointing back. This is now the enantiomer of the original compound. The procedure is described below. Determine priorities of the groups attached to the stereocenter. Swap the lowest priority group with the group that is pointing back, and redraw (this is the enantiomer). iii. Determine the absolute configuration (R or S) of the enantiomer. iv. Determine the absolute configuration (R or S) of the original compound. i. ii. Answer the following questions. Completely fill in the circle in front of your chosen answer. (a) Assign priorities of the groups at this stereocenter (1 = highest priority; 2 = second priority; 3 = third priority; 4 = lowest priority). Each group must have a different priority: CH3 Br H CH3 *Br H3CH₂C H 3 O 4 (b) The absolute configuration of this compound is: OR OS CH₂CH3 1 02
