Expert Answer
Substitution reactions are those reactions which involve substitution of a group with another. If the substituted group is a nucleophile, then the reaction is termed as nucleophillic substitution.
A nucleophile is a group which either bears negative charge (such as halides) or lone pairs (such as ammonia)
SN1 and SN2 are the types of nucleophillic substitution reactions which are differentiated as :
| SN1 reaction | SN2 reaction |
1. | SN1 stands for nucleophillic substitution reaction that is unimolecular. It means rate of reaction depends only on substrate and not the nucleophile Rate = [Substrate] | SN2 stands for nucleophillic substitution reaction that is unimolecular. It means rate of reaction depends on both substrate as well as nucleophile Rate = [Substrate][Nucleophile] |
2. | Reaction occurs in two steps i.e. a) Release of leaving group from substrate and formation of carbocation (Slow step) b) Attack of nucleophile (Fast step) As carbocations are planar, attack of nucleophile may from any side resulting in formation of two stereoisomers in equal amounts. | Reaction occurs in one step i.e. Attack of nucleophile on the substrate
Attack of nucleophile is from backward direction to avoid steric hinderance so, only one stereoisomer is formed. |
Examples of the two reactions are as below:
