First, a drying tube was attained, cleaned, and dried. It was then refilled with two puffs of cotton and calcium chloride. A dry reflux apparatus was set up as well. 1.03 g of sodium borohydride was then measured and covered by a watch glass in a 50 mL beaker. 5.57g of benzophenone was then dissolved into 50 mL of methanol in a 100 mL
