omdm reaction mechanism doubt
so I was solving this problem in omdm... In omdm a mercurinium ion (non classical) formation takes place. My teacher said that we've to break this from the site where there's more cationic character, determined by inductive and NOT mesomeric.
Then in the image I've attached, why do we break from the site where phenyl is attached. doesn't it exhibit -I effect? It is better cuz of resonance, but my teacher told we shouldnt look at that.

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.There is no notion like that
It is always the stability of the positive charge that matters in this case particularly because of how the energy profile of the reaction is
I can elaborate further when you’re online
Oh okay
Thank you...
I'll just share a problem, I solved some time ago (if i can find it)
okay.. i'll just send that problem too.. on the same rxn mech
Yeah sure do
Although you just check for the stability of positive charge as if it was there
Not much else
