The correct increasing order of reactivity for the following molecules towards electrophilic aromatic substitution is
I < IV < II < III
I < IV < II < IV
I < III < II < IV
I < III < IV < II
The corrcet decreasing order of pKb is
I > II > III > IV
III > IV > II > I
II > III > IV > I
IV > II > I > III
The correct decreasing order of pKa is
II > IV > I > III
IV > II > III > I
III > II > IV > I
IV > I > II > III
