Stereochemistry ofSN2 and SN1 Stereochemistry ofSN2 reaction: As we previously discussed, in an SN2 reaction, the attack of a nucleophile occurs to form the back side, that is, in the direction opposite to the one where the halogen leaves. As a result, SN2 is accompanied by inversion of c...

SN2 Substitution Nucleophilic Unimolecular (SN1) In this section, we will study about SN1 chemical reaction and what conditions haloalkanes require for undergoing this reaction. The meaning of SN1 reaction lies in the name itself “substitution, nucleophilic, and unimolecular.” Therefore, this...
This was ascribed to the simultaneous occurrence of SN1 and SN2 reactions without an intermediate mechanism. These results are taken as evidence for the duality of SN1 and SN2 mechanisms in the Menschutkin reaction in the non-solvolyzing solvent acetonitrile. Copyright 2001 John Wiley & Sons, ...

2. Relatively weak nucleophile (base): H2O or halide. SN1 rxns are driven by the electrophile (carbocation). 3. Polar, protic solvent: H2O or alcohol. Describe the factors that affect SN2 reactions (4) and examples. 1. Substrate without bulky substituents: primary C bearing leaving group. ...
