Worksheet #6 R340 Fall 2009 Name: ___________________ Page 1 of 3 Instructions : Read the directions to each type of question carefully . 1. For each molecule, assign the priority of the groups attached to the central carbons. Number the groups 1-4 starting with 1 for the highest priority group. Also, assign each asymmetric carbon as R or S configuration based on your priority numbering. 2. Identify the asymmetric center in the molecule below and assign it as R or S configuration.
