Properties of the Enantiomeric Carvones

Purpose To explore the physical and chemical properties of enantiomers. 

Bromine is a hazardous chemicai that may cause serious chemical burns. Do not breathe its vapors or allow it to come into contact with the skin. Perform that all operations involving the transfer of solutions of bromine at a hood and wear latex gloves when handling bromine or solutions of it. If you get bromine on your skin, immediately wash the affected area with soap and warm water and soak the skin in 0.6 M sodium thiosulfate solution, for up to 3 h if the burn is particularly serious. 

Bromine reacts with acetone to form a-bromoacetone, BrCH2COCH3, a powerful lachrymator. Do not rinse glassware that might contain residual bromine with acetone Rather, follow the procedure described in Wrapping It Up. 

Wear latex gloves to prevent solutions of potassium permanganate from contacting your skin.These solutions cause unsightly stains on your skin and last several days. If contact occurs, wash the affected area thoroughly with warm water.
