Consider the reaction scheme below NBS hv a. Draw the major regioisomer resulting from monobromination of cyclohexene with N-bromosuccinimide. If this major regioisomer is produced as a mixture of stereoisomers, draw each stereoisomer and indicate the relative amount of each stereoisomer (That is, if one stereoisomer is formed preferentially label it is as "major." If both are formed in equal amounts label each as "50%"). b. Draw an arrow pushing reaction mechanism for this reaction. You should draw an initiation step, two propagation steps, and two possible termination steps for the radical chain reaction and clearly label which step is which. Your mechanism can use Br2 as the source of bromine radicals in the initiation step that will be present as a minor, low concentration impurity in the NBS.
