Identify correct order of reactivity in electrophilic substitution reaction of the following compounds :

Options

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

Answer

C

Explanation

`NO_(2)` and `Cl` are electron withdrawing groups but `NO_(2)` is stronger electron withdrawing. Hence nitrobenzene is least reactive. `CH_(3)` group is electron releasing and hence toluene is most reactive. Hence the correct order is :
toluene `gt` benzene `gt` chlorobenzene `gt` nitrobenzene.
