1. Compound Y with a partition coefficient of 0.4 (K) between solvents A and B (as shown in the formula below) is dissolved in 100 mL of A. Which will be more effective for extracting compound Y one extraction using 80 mL of solvent B or two successive extractions using 40 mL of solvent B at the time? Show your calculations.
Partition Coefficient: K={Y}A/{Y}B
2. A mixture containing 1,3,5-trimethoxybenzene (A), phenol (B), aniline (C) and 1- naphthoic acid (D) was dissolved in dichloromethane. Next two extractions were performed first using HCl then with NaOH. Which of the compounds could not be separated in this procedure. Explain and show the pertinent reaction equation/s. (4 pts)
3.A student wanted to separate a mixture of benzoic acid and aniline that were dissolved in acetone. Could the student separate the two compounds using a base extraction (NaOH)? Explain (2 pts)
4. Acetanilide and aniline were dissolved in diethyl ether and extracted with 5% NaOH. Which of the two compounds would you expect to find in the aqueous layer? Explain your answer. (2 pts)
