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

Options

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

Answer

C

Explanation

The `-NO_(2)` groups is electron attractive group, so it deactivates the benzene ring but this deactivation is lower to `-NO_(2)` group, while `-CH_(3)` group activates the benzene ring. Hence on the basis of activation and deactivation they have the following order of electrophilic attraction (because more activated group attracts electrophilic easily).
