1) (20 pts) Draw all the isomers of C 4 H 8 Cl 2 (Note: if you have read ahead and know what stereoisomers are, we do not want stereoisomers, only the isomers that differ in connectivity). A L S O , how many units of unsaturation does this formula correspond to:_____ ZERO _____ ? Draw one isomeric structure in each of the boxes below. There may or may not be more boxes than isomers. Name C Cl H 3 C CH 3 CH 2 Cl C H ClH 2 C CH 3 CH 2 Cl C H H 3 C CH 3 CHCl 2 Cl Cl Cl Cl Cl Cl Cl Cl Cl Cl Cl Cl Remember: there are lots of ways to draw each of these molecules. Many students had duplicate structures. We did not subtract for duplicates thistime, but next time we probably will.
