Question

Though chlorine is an electro reductant agent but in substitution aromatic reaction it direct ortho and para position. why?​

Answer 1

Answer:

Chlorine withdraws electrons through inductive effect and releases electrons through resonance. ... The resonance effect tends to oppose the inductive effect for the attack at ortho- and para- positions and hence makes the deactivation less for ortho- and para- attack.

Explanation:

Hope this will help you

Answer 2

Explanation:

although chlorin is an electron withdrawing group.yet it is ortho-,para-directing in electrophilic aromatic substitution reactions...the inductive effect is stronger than resonance and causes net electron withdrawal and thus causes net deactivation
