Draw (R) and (S) 2-bromobutane. Be sure to label each enantiomer. A student uses ether to extract an organic compound from the aqueous solution in a separatory funnel. Before evaporating the ether to isolate the solid organic compound, the student adds anhydrous sodium sulfate. What is the molecular formula of sodium sulfate? What is the purpose of adding it and how is it separated from the organic layer before the ether is evaporated? After a reaction, traces of the starting material diphenylamine were left in the organic layer. Would an aqueous solution of sodium bicarbonate be effective in removing traces of diphenylamine from the organic layer? Explain your answer by showing a chemical reaction between sodium bicarbonate and diphenylamine. A crude organic compound dissolved in diethyl ether (d = 0.715 g/mL is poured into a separatory funnel. Deionized water (d = 1.000 g/mL) is added to the separatory funnel Which layer contains the product?
