I think it is yep The benzene part is aromatic, the cyclohexane part is non-aromatic So the compound as a whole has some aromaticity

oh i didnt know that was possible will the largest conjugated ring logic work here?
Nimboi
Nimboi4w ago
I'm assuming it is since the cyclohexane part doesn't "do" anything to the benzene part Like doesn't disrupt its resonance or anything like that what do you mean?

Our teacher told the same thing Aromatic + Non-Aromatic gives aromatic compound Aromatic + Anti-Aromatic gives anti-aromatic compound Anti-Aromatic + Non-Aromatic gives anti-aromatic compound

really? interesting I would've thought it'd still be aromatic since aromatic is 4n+2 pi electrons antiaromatic is 4n pi electrons if both are in conjugation you still get 4n+2 pi electrons maybe it loses planarity or something
cauchyschwartz
cauchyschwartzOP4w ago
so with that logic this should be anti aromatic

a method i was taught to check aromaticity of structure like annulene

I think so yea

Depends on how they're connected Wrong message reply. I meant to reply to the next one.

thanks guys

its aromatic bruh this is bs dont memorise oc use fused ring rule don't memorise such bs
PeriodicTable ji
Is this aromatic?
Opt
Opt4w ago
I'm pretty sure it is. The continuous conjugation condition always throws me off though

*Anti if I remember right -C=O bond is very polar so without breaking also there is effective + on carbon ig.

ig antiaromatic

anti aromatichm hoga quasi aromatic compounds type
SirLancelotDuLac
Yeah sort of.
PeriodicTable ji
What's that
Dexter
Dexter4w ago
Aromatic compounds that are formed by ionisation of a polar bond

Is this related to the original question?

Answer would be (B) due to Beyer strain theory (angle strain)

no im sorry i forgot to mention stability order of rxn intermediate thanks a lot
SirLancelotDuLac
Ah.
cauchyschwartz
cauchyschwartzOP4w ago
also i got the og question ka answer confirmed u guys are correct but no need to learn all this just know that aro is more stable

Wait...The third one should be non-aromatic right? Because one portion of that is anti-aromatic rings also?
SirLancelotDuLac
Chemistry Stack Exchange
Is a compound aromatic if it also has anti-aromatic rings?
Is 5,6,11,12-tetradehydrodibenzo[a,e][8]annulene aromatic? If I use Hückel's rule for the whole molecule, I get the answer as anti-aromatic. But the compound has two benzene rings which are indivi...

cauchyschwartzOP4w ago
but i asked a teacher and she said ki it will be considered aro because aromatic structures are morw stable therefore more dominating
PeriodicTable ji
How is it more stable exactly
cauchyschwartz
cauchyschwartzOP4w ago
arey aromatic are obviously more stable than anti aromatic look up what aromatic and anti aro means
PeriodicTable ji
No I mean, why is the stability overpowering the unstability of anti aro
cauchyschwartz
cauchyschwartzOP4w ago
well im not sure about that but i was just told that a compound always wants to be stable so if the compound has an aro structure it will be stable i know this isnt exactly the answer but i think what ure looking for is not in syllabus for jee
PeriodicTable ji
Alright thanks
