- The electrophilic addition of HBr to 3-cyclohexylbut-1-ene gives a mixture of two constitutional isomers. These two isomers can also be produced from 3-cylcohexybut-2-ene, but one of which requires different reaction conditions; the electrophilic addition of HBr to 3-cylcohexybut-2-ene produces one of these isomers while the electrophilic addition of HBr to 3-cylcohexybut-2-ene, in the presence of peroxides, produces the other one. Draw the structure for the isomer product that can result from the reactants 3-cyclohexylbut-1-ene and 3-cylcohexybut-2-ene using different reaction conditions.
