1. one method for favoring the formation of an ester is to add excess acetic acid. suggest another method, involving the right-hand side of the equation, that will favor the formation of the ester. 2. why is it easier to remove excess acetic acid from the products than excess isopentyl alcohol? 3. why is the reaction mixture extracted with sodium bicarbonate? give an equation and explain its relevance. 4. which starting material is the limiting reagent in this procedure? which reagent is used in excess? how great is the molar excess (how many times greater)?
