An arrow is also needed to indicate the loss of the leaving group.b. The arrow indicating the formation of the C-Br bond (nucleophilic attack) should start at the bromide anion.c. There is no leaving group, so there should be no arrows.

The use of curved arrows is a powerful tool that illustrates even complex reactions. a.Add curved arrows to show how carbocation A is converted to carbocation B. Label each new σ bond formed. Similar reactions have been used in elegant syntheses of steroids. b.Draw the product by following the curved arrows. This reaction is an example of a [3,3] sigmatropic rearrangement, as we will learn in Chapter 25.

During the workup portion of the reaction of alkenes with HBr as described in the experiment provided, a student transferred the reaction mixture to a separatory funnel, rinsed the reaction flask with diethyl ether, and added the ether rinses to the separatory funnel. The student then added sodium bicarbonate to the separatory funnel. Extremely vigorous bubbling occurred. What did the student do wrong? Can they still isolate the product? If so describe the next steps the student should take to isolate the product.
