MP۲ c ompariso n of the effect of Flu orine and Amine groups on kinetics th e of carbocation formation

The alkane which substituted with one or mo re halogen atoms such as chlorine o r fluorine named as haloa lkanes. The important type of haloalkanes is CFC compound. The CFC s are chloroflu orocarbons which co ntain chlorine and fluorine and were used as refrigerants, propellan ts for aerosols, for generating foamed plastics like expanded polystyrene or polyuret hane foam, and as solvents for dry cleaning an d for general degreasing purposes in last century. Unfortunately, in high atmosphere, the carbon chlorine bonds break to give chlorin e free radicals which destro y ozone an d so CFCs are largely responsible fo r destroying the ozone l ayer. Studying the chemistry of hal oalkanes can be usef ul for unde rstanding the chemist ry of atmosph ere[۱,۲] and many researchers w ork to kno w the chem istry which taken place in haloalka ne [۳,۴,۵]. In this resea rch effect of the fluor ine and amine groups on the kinet ic of formation of carboc ation from haloalkane a nd E۱ reac tion which compete to each others were studied by MP۲ Methods.
