Through SN1 mechanism, racemisation takes place because of the formation of carbocation in the first step.
SN1 takes place through two steps.
In the first step, the leaving group ( the halide ion) leaves the carbon and a carbocation is formed. A carbocation is planar.
Thus, in the second step, the attack of the nucleophile on the carbocation can take place from both the sides - front attack and back attack.Thus, a racemic mixture is formed.
