Question

The correct arrangement for decreasing order of reactivity towards electrophilic substitution reaction is:

• A. III > I > II > IV
• B. IV > I > II > III
• C. III > IV > II > I
• D. II > IV > III > I

Answer 1

The correct option is A III > I > II > IV

The decreasing order of reactivity is

$III>I>II>IV$

Greater the electron density on Benzene ring more will be its reactivity towards electrophilic substitution reaction.
