+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.my book says 1-bromocyclohex-2-ene
ai says bromocyclohexane
i think it should be ,4-dibromocyclohexane
yeah so free radical will attack on double bond making it a bond with the one c and other will have one free electron and tht will move to para cuz of elctron density makng
this
my attempt
I think the reason for that is homolytic cleavage of the double bond here requires more energy as compared to formation of a free radical next to the double bond (which is very stable die to resonance.). So, 1-bromocyclohex-2-ene would be the major product.
could be yeah but how will i know in a reaction in general ki kab aisa hoga?
You could just remember free radical halogenation as halogenation of sp³ carbon.
Ok the other hand, you could remember that the bond dissociation energy of a C-C double bond is 682kJ/mol while C-H bond dissociation energy is 337.2kJ/mol but that's illogical
ok thnks
