Hi I'm currently studying ochem for my pharmacy entering exam in korea.
I was studying about sn1 and sn2 reaction in allylic position.
My teacher told me that if theres carbonyl beside carbon(that you will add nucleophile) it reacts with SN2 reaction then SN1
I was pretty sure that is right cuz of carbony react as Ew
WG.
But how about normal allylic? I googled it but some site said sn1 is major and some said sn2 is major...
I personally think SN2 is major cuz of the stablitiy of transition state in SN2.
BUT.. thinking about SN1 I was so counfused because there is conjugation and resonance..
Which one is major in allylic halide?
Sorry for my bad eng
