Rate of EAS propto Nucleophilicity of aromatic ring propto EDG (electron donating group) propto (1/ text EWG ) (electron withdrawing group) <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/94bc0c7a61cf0c8e067c70e019a1e3db-.png" />

Q. Correct order of rate of EAS (electrophilic aromatic substitution) ?

c > b > a > d

c > d > a > b

a > b > c > d

c > d > b > a

Rate of EAS $\propto$ Nucleophilicity of aromatic ring $\propto$ EDG (electron donating group)
$\propto \frac{1}{EWG}$ (electron withdrawing group)

Q. Correct order of rate of EAS (electrophilic aromatic substitution) ?

c > b > a > d

c > d > a > b

a > b > c > d

c > d > b > a

Rate of EAS ∝ Nucleophilicity of aromatic ring ∝ EDG (electron donating group) ∝ EWG 1​ (electron withdrawing group)

Rate of EAS $\propto$ Nucleophilicity of aromatic ring $\propto$ EDG (electron donating group)
$\propto \frac{1}{EWG}$ (electron withdrawing group)
