Solution
reaction:-
It is a nucleophilic substitution reaction, in which stable carbocation is formed.
The rate of reaction is directly proportional to the carbocation stability in the reaction.
There is basically a two-step reaction in this reaction and the intermediated formed in this reaction is basically a carbocation.
When a nucleophile attacks the carbocation in the reaction, two products would be formed.
One product will have the same configuration as there before the reaction and the other formed product will have an inverted configuration which will lead to partial racemization.
Step 1:
In the first step in this reaction, there would be cleavage of bond.
This will lead to the removal of leaving group and the formation of carbocation
Step 2:
Now the stable carbocation would be reacted by the nucleophile.
Nucleophiles will attack the central carbon which is the most stable
Step 3:
As the last step deprotonation will take place
And there will be the formation of alkyl chloride.
Chiral centre:-
It is actually an atom in the molecule which is bonded to the four different species.
The atom which is bonded to four different species has single chirality.
Therefore, in a reaction of alkyl halide on chiral centres, there is inversion more than retention to partial racemization.
