Products from Electrophilic Addition Reactions of Dienes

Draw the major 1,2- & 1,4-products from each of the diene reactions shown below. Draw each product (1,2- & 1,4-) separately, and evaluate that answer before continuing.
To draw a formula use the drawing window opened by the Draw Formulas button. Do not draw hydrogen atoms, and do not try to specify double bond configuration. When you are finished, Submit your formula and then check it by pressing the Check Product button under each question.
