When enantiomerically pure (R)-3-methyl-3-hexanol is exposed to HBr, a racemic mixture of 3-bromo-3- methylhexane can eventually be isolated. Water forms as a byproduct of this reaction. This overall transformation is shown below: HO CH 3 ( R )-3-Methyl-3-hexanol H Br Br CH 3 + H 3 C Br + H 2 O ( R )-3-Bromo-3-methylhexane (50%) ( S )-3-Bromo-3-methylhexane (50%) (a) Propose a reaction mechanism to account for formation of both enantiomers of the alkyl halide
