1. For a mixture of pure hexane and pure dimethylformamide, the dimethylformamide layer will be found as:.a. the top layer. b. the bottom layer. c. neither; the two solvents are miscible. d. cannot determine.2. To extract aniline (CeH5NH2) from a solution of chloroform, one would use:.a. aqueous HCI. b. aqueous NaOH. c. aqueous NaHCO3.d. either b or c would work.3. For mixture of methylene chloride and diethyl ether, the diethyl ether layer will be found as:.a. the top layer. b. the bottom layer. c. neither; the two solvents are miscible. d. cannot determine.4. To extract benzyl alcohol (CeH5CH2OH) from a solution of chloroform, one would use:.a. aqueous HC b. aqueous NaOH. c. aqueous NH3.d. either B or C would work.5. A large partition coefficient for the extraction of naphthalene into diethyl ether from water means that naphthalene will be found:.a. only in the water layer. b. only in the diethyl ether layer. c. mostly in the water layer. d. mostly in the diethyl ether layer.
