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.from my understanding we have to compare stability of carbanion
benzoic acid > metha>eth>prop hona chahiye then
but given ans is benzoic>eth>prop>meth
Methanoic acid doesn't have a carbanion. It can't decarboxylate at all, it can only be oxidised.
It's formic acid na?
yepp
how to compare then
You got the rest right
It's just that formic acid can't be decarboxylated at all
so its automatically at the end
?
what bout this tho
Yes
given ans is wrong then
?
Given is correct
Benzoic because resonance stability, then acetic and propanoic based on chain length, then formic because it cannot be decarboxylated in the first place.
alr got it
