Some important notes:
• Draw the major product, or products, of this reaction in the drawing area below.
• You can draw the products in any arrangement you like.
• Pay careful attention to the reaction conditions, and only include the major products.
• Be sure to use wedge and dash bonds when necessary, for example to distinguish between major products that are enantiomers.
• Note that there is only 1 equivalent of HBr reactant, so you need not consider the case of multiple additions.
