Using curved arrows to show the movement of electrons, draw plausible mechanisms for each of the following reactions. Be sure to include all important intermediates and draw all resonance structures. If the mechanism has geometric constraints, such as the E2, be sure to clearly show that in your drawing. ELONA + B + ELOH EtOH B. Why one product? Be sure to draw the chair cyclohexane and show the geometry of this reaction.
