Hemiacetals (e.g. molecule on left) are great ways to "protect" ketones and aldehydes, partly due to the fact that they interconvert fairly easily. Provide a plausible mechanism for the reaction below. Use the arrows to show the movement of electrons, and all intermediates formed during the mechanism. (note - this mechanism likely only needs two steps, starting with an E2-like step). (8 pts) 0 OH 1. NaOH . 2. H3O+
