The letter SN stands for nulceophilic Substitution, the number 2 stands for bimolecular, with both reactions partners are involved in the reaction rate determining step. It also exists an SN1 reaction; here, only one reaction partner is involved in this step. On the other side, SN2 reactions are characterized by exchanging substituents. The substituent that leaves the molecule is called leaving group. Typically, alkanes with a substituent in primary position undergo SN2 reactions. In contrast to a SN1 reaction, no stable carbo cation can be formed, therefore, another way is taken. The SN2 by establishing a so called intermediate state, with both educts comeing close to each other. By this, the bond of the leaving group is partly broken, and the bond to the new group is partly formed. The formation of this intermediate state is the rate determining step of the reaction. In the , the bond of the leaving group is completely broken, and at the same time the bond to the new substituent is completely formed. The SN2 reaction has a very interesting stereochemistry inversion of the stereocenter with an animated example of the substitution of chloride and methanol shown.
