Question figure
  1. Option A:

    B>C>A>D\mathrm{B}>\mathrm{C}>\mathrm{A}>\mathrm{D}

  2. Option B:

    D>C>B>A\mathrm{D}>\mathrm{C}>\mathrm{B}>\mathrm{A}

  3. Option C:

    A>B>C>D\mathrm{A}>\mathrm{B}>\mathrm{C}>\mathrm{D}

  4. Option D:

    B>A>C>D\mathrm{B}>\mathrm{A}>\mathrm{C}>\mathrm{D}

    Correct

Answer: D

Step-by-step solution

−CH3-\mathrm{CH}_{3} shows +M and +I .

-Cl shows +M and -I but inductive effect dominates.

−NO2-\mathrm{NO}_{2} shows -M and -I .

Electrophilic substitution α1−M and −I\alpha \frac{1}{-\mathrm{M} \text { and }-\mathrm{I}}

α+M and +I\alpha+\mathrm{M} \text { and }+\mathrm{I}

Hence, order is B>A>C>D\mathrm{B}>\mathrm{A}>\mathrm{C}>\mathrm{D}.
