Bromination of Alkenes
mass of trans-stilbene = 0.30g

products are meso-1,2-dibromo-1,2-diphenylethane and with mp of 238 deg C and 110 deg C

Molecular weight = 340.058 g/mole

mass of trans-cinnamic acid = 0.45g

Products are erythro-2,3-dibromo-3-phenylpropanoic acid, mp: 203 deg C and threo-2,3-dibromo-3-phenylpropanoic acid, mp:94 deg C

Molecular weight = 307.969 g/mole

10% Br2/CH2Cl2 = 2.0mL for both reactions

3.5 mL methylene chloride for both
