Explain about sN1 mechanism in chemistry 12
The SN1 mechanism (Substitution Nucleophilic Unimolecular) is a two-step reaction where the leaving group first departs, forming a carbocation intermediate.
Next, a nucleophile attacks this carbocation to form the final product.
It usually occurs in tertiary alkyl halides due to the stability of the carbocation.
The reaction rate depends only on the concentration of the substrate, not the nucleophile.
The sn1 mechanism is a two step substitution reaction in which :
1) the leaving group leaves first,forming a carbocation - slow step
2) the nucleophile then attacks the carbocation - fast step
The reaction rate depends only on the substrate, and it often results in a racemic mixture because the nucleophile can attack either side of the carbocation.
