(A) Both are soluble in NaOH, hence inseparable. (B) Only benzoic acid ( C 6 H 5 COOH ) is soluble in NaOH and NaHCO 3, while benzyl alcohol ( C 6 H 5 CH 2 OH ) is not. Hence, separable. (C) Although NaOH can enable separation between benzyl alcohol ( C 6 H 5 CH 2 OH ) and phenol ( C 6 H 5 OH ) as only the later is soluble in NaOH. However, in NaHCO 3, both are insoluble. Hence, inseparable. (D) α-phenyl acetic acid ( C 6 H 5 CH 2 COOH ) is soluble in NaOH and NaHCO 3. While benzyl alcohol ( C 6 H 5 CH 2 OH ) is not. Hence, separable.
