Question 1
Find the suitable base for the following reaction:
C6H5OH + :B → C6H5O:- + H:B+
The pKa for C6H5OH (phenol) is 9.88. The formula for the base is followed by the pKa of its conjugate acid.
◦ OH-, pKa = 15.73
◦ CN-, pKa = 9.31
◦ CH3C(=O)CH3, pKa = -7.2
◦ CF3COO-, pKa = 0.23
◦ CH3COO-, pKa = 4.74

◦ III > I > II
◦ II > I > III
◦ II > III > I
◦ I > II > III
◦ III > II > I
