in electrophilic aromatic substitution reaction. Explain why it is
so? .... answer fast...

Chlorine has lone pair so it shows resonance over the ring and increase the electron density on ortho and para position so it is ortho and para directing for electrophilic substitution reaction.

Hey folk...
• Being a very elctronegetive element chlorine withdraws electrons through – I effect and donate electrons through resonance(+R).
• As we know resonance is dominating over inductive but in case of halogens inductive is dominating over resonance so, chlorine is slightly electron withdrawing via inductive but it act as o, p directing group bcoz of presence of lone pair.
• One of the lone pair of electrons of chlorine can conjugate to the ring and direct the electrophile to the ortho and para positions of the ring.
Thank you

But in the case of halogens inductive effect dominates so u can't say here that resonance effect donates
Resonance is due to the presence of lone pairs
ya u r right sis wait m editing
ok
