An unknown mixture (dissolved in diethyl ether) contains only 2 of the following : benzoic acid, phenol, aniline and napthalene. You use the acid-base extraction method and want to identify the 2 compounds in your original mixture. 1) To separate the organic acid you add NaOH and to separate the organic base you add HCl.In both cases these extractions are followed by extractions with water. Why do we add water? Why is this step important? (A clear explanation please). 2)When...

Suggest a flow chart for the separation of a mixture of benzyl alcohol and benzoic acid using extraction procedure. (4 marks) Hydrolysis of compound A2 (CH 403) gave A3 and A4, A3 can be obtained from a reaction of 1-bromobutane with NaCN followed by acid hydrolysis. A reaction of A4 with thionyl chloride (SOCl2) afforded A5. Treatment of A5 with 2-propanol yielded A6. Deduce the structures of A2 to A6. (5 marks)

You have 100 mL of a solution of benzoic acid in water; the amount of benzoic acid in the solution is estimated to be about 0.30 g. The distribution coefficient of benzoic acid in diethyl ether and water is approximately 10. Calculate the amount of acid that would be left in the water solution after four 20-mL extractions with ether. Do the same calculation, using one 80-mL extraction with ether, to determine which method is more efficient.
