Draw the unique stereoisomers for 1,2-difluorocyclohexane. show stereochemistry clearly. to ensure proper grading, explicitly draw all four groups, including wedge/dash bonds, around a chirality center. indicate whether the compound(s) could exist in an optically active form.

28. which is not a reason that water is used to store spent fuel rods from nuclear power plants? water increases the speed of the chain reaction in the fuel rods. water protects nuclear power plant workers from the high temperature and radiation of the fuel rods. water acts as a radiation shield to reduce the radiation levels. water cools the spent rods. salts action
