HI ALL.. HAPPY MORNING... Today I wanna share with you some useful notes for the chemistry students regarding Elimination Reactions in organic chemistry(Part-1) #Elimination reactions in organic chemistry involves removal of two groups/substituents from adjacent carbon atoms to form new Pi bond(π). Practical point of view these reactions are useful for generation of double/Triple bonds in compounds from a saturated starting Material. Eg: Dehydro halogenation of Alkyl halides to alkenes can be the best example here to explain well. E limination Reaction goes through following events . removal of a proton formation of the C-C π bond leaving group(Halide group) bond breaking Different mechanisms are possible due to time interval between different events E2 Reaction:Simultaneous removal of H + ,formation of new C=C bond and loss of the halide group(Leaving Group) -Involve s One step E1 reaction:Formation of carbocation by removal of leaving group followed
