(2 3 C. (a) Construct four models of the compound CH,CHCICHBRCH3. Take two models and hold them with the two CH3 groups away from you. Now arrange the CI on C-2 and the Br on C-3 so that both groups are on your right on one model and both are on your left on the other model. Test to see if these models are superimposable or are enantiomers (mirror image isomers). Draw projection formulas for these models. If they are the same, only one structure needs to be drawn. If they are enantiomers, draw both structures as mirror image isomers.
