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.Free radical halogenation
Halogenation occurs on all sp³ hybridised carbons present, but with higher yield of those where the free radical is resonance stabilised
You generally consider major product.
yeah but why does br attach to ch3 and not no2?
and in vi the br is attached to c next to double bonded c
but no2 will hve resonance na
You can't generate a free radical on NO2
You generate a carbon free radical on specifically an sp³ carbon by attacking the hydrogen connected to it with a halogen free radical.
uh huhh okk
So, it's sp³ C-H + X• → sp³ C• + HX
then cuz its double bond it will attch to c next to it in vi?
The C-H bond undergoes homolytic cleavage because the electronegativity of sp³ carbon and hydrogen is nearly the same
right
yhh
This isn't possible for sp² carbons since they have greater effective nuclear pull on the bond electrons
okk
And other sp³ carbons too, but smaller yield, minor product
So you can neglect
The allylic free radicals are resonance stabilised
oh ok thnks
