(1) Predict the outcome of the addition of HBr to (a) trans-2-pentene, (b) 2-methyl-2- butene, and (c) 4-methylcyclohexene. How many isomers can be formed in each case? (2) Addition of HBr to 3,3-dimethyl-1-butene gives a mixture of two isomeric alkyl bromide products. Draw structures for the two products, and give a mechanistic explanation for their formation.
