For each of the following reactions diagram the steps from the substrate to the product. For each step, a) over the reaction arrow supply the needed reagents b) name the type of reaction/mechanism {ROS (SN1, SN2, radical) E(E1, E2) A [acid-base, addition (carbocation, onium bridge, radical)]}
Why is concerted syn addition needed in the first step of X2 addition or mercurinium formation? 1.Syn addition occurs on both sides of the alkene bond to prevent cation formation and create a lower 2.energy interemdiate. 3.The alkene attacks the X2 from the top and bottom faces equally. 4.Only one face of the alkene can interact with the reagent. 5.No answer text provided.
