(Solved) difference between stereochemistry of sn1& sn2. The EtO-ion sits between the region of large and small bases and will do either E2 or SN2 reactions depending on the substrate used. As long as the substrate is hindered enough, E2 reactions will predominate, but there is always the risk of SN2 by- products. Proper Orientation - Perhaps the most important aspect of E2 elimination is the need forproper orientation of the molecule. E2 reactions, In both nucleophilic substitution reactions (mixed sn1 and sn2), there is a competition between the leaving group and the nucleophile..

Reactions of Alkyl Halides The alkyl halides are chemically versatile. The halogen atom may leave with its bonding pair of electrons to give a halide ion which is stable – a halide is called a good leaving group. If an atom replaces the halide the overall reaction is a substitution. If the halide loss is accompanied by the loss of another atom, the overall reaction is called an elimination
