- The transformation below takes place by two distinct reactions. Intermediate A is formed in the first reaction and then this goes on to the product in the second reaction. Provide a complete curved-arrow mechanism for all steps of both reactions.arrow_forwardFor each reaction, predict what mechanism will account for the major product(s) formed and write (SN1, SN2, or NR) in the boxes provided. Explanations or drawings are not required.arrow_forwardTreatment of 1,2-dibromoethane with the dithiolate dianion shown in the reaction below leads to two products as shown. Draw the structure for each molecular formula and provide a detailed mechanism for the formation of both products.arrow_forward
- Please give the Major product(s) of the reaction only and state the mechanism the reaction follows (SN1, SN2, E1, E2)arrow_forwardComplete the following reactions by providing the missing product(s). Determine what mechanism operates in each case (SN1, SN2, E1, or E2). Show the stereochemistry of the product(s) where appropriate. If more than one product is formed circle the major one.arrow_forwardPredict the product and draw a detailed mechanism for the transformation.arrow_forward
