Draw the major organic product(s) of the following reaction. You do not have to consider stereochemistry. If no reaction occurs, draw the organic starting material. When SN1 & E1 pathways compete, show both the substitution and the elimination products. Separate multiple products using the + sign from the dropdown menu. Do not include counter-ions, e.g., Na+, I-, in your answer. Cl CH3OH
