NO2 groups can accept a pi bond from the aromatic ring, making it more electron poor.

That’s awesome but I don’t understand why NO2 is meta director while NH2 is Ortho para director

I used to be quite confused about how I- could be the best nucleophile and the best leaving group at the same time XP
thank you for these explanations!

H is the least electronegative element. Search its effective nuclear charge. Does it was do be anionic?

In reply to Vamsi.

Yes – check out this on nucleophilic aromatic substitution.

In reply to mycoxsmall. No. Fluoride ion is a good nucleophile, but is not a good leaving group.

Could you please explain why H- is a strong base
I guess it has noble gas configuration so won’t donate it’s electron
Please clarify.

If NH3 is more basic than H2O than how is it a Better leaving group than H2O
