Draw a mechanism for this reaction.

The reaction typically takes place at between 40-65°C. As the reaction temperature goes higher, the rate of reaction will increase, typically 1-2 hours at 60 °C versus 2-4 hours at 40°C. If the reaction is higher than 65°C, a pressure vessel is required because methanol will boil at 65°C. It also helps to increase the methanol-to-oil ratio.Question: 3.46 For each reaction below, draw a mechanism (curved arrows) and then predict which side of the reaction is favored under equilibrium conditions: ОН HO + ol (a) HOH (b) ~ SH + + 2 OH SO H.S urs aw (c) SH = 1.
