Evaluating Curved Arrow Mechanisms

Select a problem from the list on the right. When the Show Problem button is pressed a curved arrow mechanism will be shown below. Using the drawing window, draw a structural formula (or formulas) for the compound(s) or ions formed by this mechanism. If more than one species is formed in the reaction draw them all using the New button to start a second component. Small ions are drawn by pressing the element symbol on the left, with charges designated by using the +/- button. Do not try to designate the configurations of chiral centers or double bonds.
To evaluate your answer press the Check Answer button. A response will be presented in the information window.
