QUESTION 2 To facilitate the transesterification process to form biodiesel, we utilize sodium methoxide. Why don't we just use a solution of sodium hydroxide? O NaOH is too basic, resulting in a series of elimination reactions with alkenes as the products. The methoxide becomes the new ester. The hydroxide with generate a carboxylic acid derivative that would react and form soap. NaOH wil cause the transesterification process to go completely in reverse and thus stop the formation of biodiesel Sodium...
