Createa flow chart separating phenol (P, pKa= 10.0), benzoic acid (B, pKa= 4.2), and diphenylmethanol (D, pKa~ 16) by extraction using ether, Et2O, as the solvent. All three compounds are more soluble in ether than water. In your lab, you have aqueous HCl, NaOH, and NaHCO3readily available. (Useful pKas: H2O = 15.7; H2CO3= 6.4)
