The Correct Option is B
Solution and Explanation
The correct answer is option (B) : aq. NaHCO3 + n-hexane
PhCOOH and PhCH3 can be separated by Aq. NaHCO3 + n-hexane. This method is the acid-base extraction method.
When NaHCO3 is added to the mixture, benzoic acid will react with NaHCO3( a weak base) to form soluble sodium benzoate.
After this, the non-aqueous layer will contain toluene.
