Yield of Reaction
Propene reacts with hydrobromic acid to yield 2-bromopropane via Markovnikov addition about the double bond of the alkene. The organic halide then reacts with 2-propanone(acetone), Mg metal and hydrochloric acid via Grignard reaction to yield 2,3-dimethyl-2-butanol. Write the chemical equations for these reactions using line drawings to represent the organic compounds (there are only three structures and two equations). If you are given 1.00 mol of propene and 1.25 mol (excess) HBr, a 79.0% yield would give you how much 2-bromopropane? If the calculated amount of 2-bromopropane above is combined with excess acetone, excess Mg metal and excess acid as a work-up, how much 2,3-dimethyl-2-propanol would you expect from an 83% yield?
