NEETChemistryHaloalkanes and Haloarenes
Although chlorine is an electron withdrawing group, yet it is ortho-, para- directing in electrophilic aromatic substitution reactions. Why?
Options
- AChlorine donates electrons to the benzene ring, increasing electron density at the ortho and para positions.
- BChlorine's electron-withdrawing effect enhances the nucleophilic attack of the electrophile at the ortho and p
- CThe inductive effect is stronger than resonance and causes net electron withdrawal and thus causes net deactiv
- DChlorine's electron-donating effect on the benzene ring makes it a meta-directing group in electrophilic aroma
Correct answer
C. The inductive effect is stronger than resonance and causes net electron withdrawal and thus causes net deactiv
Step-by-step solution
Correct Option is : (C) The inductive effect is stronger than resonance and causes net electron withdrawal and thus causes net deactivation. 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.
