Question
1. Assuming that the extraction of the 30 mL 1-octanol solution containing 1.00 g of o-Cresol is done with 30 mL of NaOH(aq), and that all the o-Cresol is converted into sodium o-cresoxde; how much of the original o-Cresol is in the aqueous layer?
2. Assuming that the extraction of the 30 mL 1-octanol solution containing 1.00 g of o-Cresol is done with two 15 mL aliquots of NaOH(aq), and that all the o-Cresol is converted into sodium o-cresoxde; how much of the original o-Cresol is in the aqueous layer?

As in both the cases the work up of were done by aquous solution of NaOH and in both the cases it is asumed that the amount of O-creasol was converted completely to it Na-salt equivalent and nothing is left to the organic layer so it is easily concluded that in both the cases irrespective of the amount of water taken the there will be no trace of O-creasol left to the organic layer. Just consider the amount of 1 equivalent of 1 creasol reactant is coverted to its 1 equivalent of product with 100% yield.
