conjugate base mein x aur z dono aromatic ho jayenge but -CN -m effect show karta hai thus decreasing the -ve charge and less aromaticity
thus making x anion more stable than z and x a better acid than z
@Dexter
Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.hmmmmm sahi lagraha hai mujhe ye to
ans is z>x>y sadly
"Decreases the aromaticity" part is wrong imo. The ring is still aromatic and -CN is just helping to ease the -ve charge.
so it is kinda neutralizing some of -ve charge
and in x theres complete -ve charge therefore better aromaticity
There should just be -ve charge/conjugation for it to be aromatic.
For example, would you consider phenol less aromatic than benzene? No.
so phenol is more stable than benzene ??
Z is more acidic bc CN will take electron thereby making the H more acidic
No. I was just saying that by resonance edg or ewg just decreases the electron density. It doesn't have effect over aromaticity.
observe that this -ve charge is helping both in aromaticity and conjugation with C triple bond N {Aromatic+Conjugation}
@hardcoreisdead both x and y become anti aromatic
After deprotonation
Y is non planar
And x has 4 pi electrons
X to aromatic ban jaaega
4n+2?
Yeah
-ve charge aata hai deprotonation ke baad
Fuck
🐴
Ha bhai tab to z x y is decreasing order
yeh logically correct nahi hi hai then ig
