GOC carbocation stability
OR group gives +M
straight up R group gives +I
how to actaully find out which one is more stable??

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.I don't think that species will even exist without rearranging into something else.
its not about existense just stability terms
damn mujhe bhi C laga
haina
cuz like
reso
+M for ring
that too
if C is wrong, is it because OCH3's -I effect outweighs its +M at ortho (since distance in ortho is less)
i've only seen such a thing happen in halogens
okay oxygen is more electronegative than chlorine so that may be the case
But we also have a CH3 attached to it so wouldn't that make it difficult to compare?
my original answer was C but apparently D is correct ¯\_(ツ)_/¯
wait difficult to compare in the sense?
-OCH3 is a group on its own
Like whether the net effect would be withdrawing or not as in case of halo
this is like
comparing apples and oranges

Activating and Deactivating Groups In Electrophilic Aromatic Substi...
What are activating and deactivating groups in organic chemistry? Here we explain these terms, provide a list of activating & deactivating groups, and more!
According to this -OH would be the most electron withdrawing.
Shouldnt that be the case only with halogens though
C hona chahiye
💔
In this case the positive charge is on benzene carbon itself, maybe something to do with it
OHHHH YEAHH
The benzene
carbon ka
p orbital is
out of the
plane
no resonance there
😭🙏
so inductive se hi answer hoga
I don't get that? No hybridisation?
sp² hai na carbon
to ek p orbital is still left
Oh I see
that p orbital is perpendicular to the sp2 plane
@Phalawor
I don't get it
Wait a few hours bro I got my eyes dilated can't see anything clear
god i hate that
i've never heard of this before wow
orbital diagram dekhna padega
ruko
aisa kuch
isnt -oh the most ewg making it B
ahhh oke
thank u dexter bhai
Ring ke plane mein resonance act nahi krta
the +ve charge stability will be determined by inductive effect only
yea prob coz och3's -i effect
wait isnt it because of incomparable size? like F and C are comparable so their resonance is more evident unlike Cl
no
whenever +ve charge is in the plane of the ring resonance doesn't act on that
the electrons are delocalised in the plane perpendicular to the ring
oh wait sorry i read it wrong
i thought u were talkin about cl
but what i said is correct i think
resonance is more evident with flourine
yeah thats true
achcha haa sp2 hai na ye to
got it got it so we cant use M effect so inductive is ony choice and Inductive to only Rgroup ka +I is most stonks
tell me if im wrong but
c mein conjugation hai toh lp of Oxygen delocalise ho jayenge and uspe fir delta postive aa jayega and positive on electronegative is unstable toh c rule out ho gya
@Phalawor
but idhar to carbocation ka poocha hai you cant just go into uska resonance structure na
youve gotta look at the OG thing
and then judge it
thats what ive built
hmmm
then what is the reason
can u send the og question please
idk i dont go into resonance structure stability of a given structure
mene kuch galti krdi i didnt understand the question
mereko lga overall ki batani hai
it was Carbocation stability the structures are too big for one photo
haan
got it
yea 4 were there these 2 were doubtful
yea man my major doubt was just that how do we compare R and I groups
C has R and D had I
got it tho
thanks
+I ka theres an order na
vahi show krenge +I the ones u mug up basically
ayo why is this still open
