Consider the following reaction: OH HC H.SO CH, + ОН Δ Show the complete mechanism for the following transformations. Make sure to show all arrows depicting the movement of electrons. The above reaction (using acid and heat) causes a number of unwanted side products to form (a big mess). Propose a better synthesis for the product using the same starting materials. Show the reagents and intermediate steps to complete the synthesis: OH H3C- ??? + CH3 OH X steps Propose...
