(a) The bromohydrins produced by exposure of cis-2-butene to bromine water have two chirality centers and no symmetry, so can exist as four configurational isomers (RR, SS, RS, and SR). Just two of these four possible isomers (the enantiomeric RR/SS pair) are in fact produced, as shown below: н, „Н Вг, в н н Во C-C...H CH, H2OH-S3 + HCA - Ho's s cH, HE R ROH Write a curved arrow mechanism, including a cyclic bromonium ion intermediate, that accounts...
