1. Make a model of each compound, draw it in its most symmetric conformation, and determine whether it is capable of showing optical activity.
(a) 1-bromo-1-chloroethane
(b) 1-bromo-2-chloroethane
(c) 1, 2-dichloropropane
(d) cis-1, 3-dibromocyclohexane
(e) trans-1, 3-dibromocyclohexane
(f) trans-1, 4-dibromocyclohexane
2. Star (*) each asymmetric carbon atom, label each as (R) or (S), and compare your result from part (1) with the prediction you would make based on the asymmetric carbons.
