11 The mechanism of bromination of an alkene, which involves a cyclic bromonium ion, explains why trans-2-butene and cis-2-butene give rise, respectively, to a meso structure and a racemic mixture of 2,3-dibromobutanes Me Brz Me Me Br trans-but-2-ene Meso product Bra Me Me cis-but-2-ene Racemic product 1. Make a model and draw the structure of the cyclic bromonium ion that results from addition to trans-2-butene 2. Make a model of the meso structure that results from opening of this bromonium ion by an SN2 mechanism 3. Assign the configuration at each centre of the structure you have drawn
