IMO it should be A
Imo also a
The NO2+ will attack upper side of double bond and carbocation will form near O which will be stabilized by it with mesomeric effect.Right?
Yeah I was also thinking along the same lines
The carbonation will undergo resonance
So place doesn't matters
The no of resonation structures will proceed the rxn
And a has 3 resonance structure and b has only 2
Ya I get what you are saying.
Maybe it has something to do with -I of O?
Should be A imo
Yeah this is what I found on google
I think it will not work here because there is absence of acoh and also pyridine also I couldn't understand what is that structure containing no2? I think it is ch3coono2...does any compound exist like that? I have not seen before
It's the same thing you can replace acoh with h2so4.
And yes the compound exist and is used in nitration like shown in the mechanism
But all these compounds aren't given here
So why not a?
It should be A ignore my above post
Thanks a lot
