5. John and Jane used 0.70 g of NBS (N-bromosuccinimide) (mw = 177.98g/mol) and 0.48 mL of 1-methylcyclohexene (density = 0.811g/mL, mw = 96.17g/mol) in their preparation of the bromohydrin (Experiment 10). They obtained 0.70 g of crude bromohydrin (mw = 193 g/mol). After they split the product, Jane received a vial containing 0.40 g of the crude bromohydrin. She used the column chromatography to purify the crude product and obtained 0.30 g of pure bromohydrin. (a) Determine both percent...
