Question

The decreasing order of reactivity towards electrophilic substitution reaction of the following compounds is

A. `1 gt 3 gt 4 gt 2`
B. `4 gt 1 gt 3 gt 2`
C. `4 gt 1 gt 2 gt 3`
D. `4 gt 2 gt 1 gt 3`

Answer 1

Correct Answer - C
`-CH_(3)` is electron donating group, shows +I effect `-NO_(2)` is electron withdrawing group as well as shows -M effect.
-Cl shows -I effect and is a weak deactivating group so the order of reactivity towards electrophilic substitution reaction is
