Can someone please explain me about racemization in SN1 and SN2, the main idea we need to know for the mcat. And also this question please:
The reaction RBr + Br*→ RBr* + Br is always accompanied by inversion. If this reaction is carried out on an optically pure sample of a chiral compound, which of the following statements will be true? [Note: Br* represents a radioactive isotope of bromine.]
A - The rate of Br* incorporation is half the rate of racemization.
B - The rate of Br* incorporation is equal to the rate of racemization.
C - The rate of Br* incorporation is twice the rate of racemization.
D - The relation between the rate of Br* incorporation and the rate of racemization cannot be determined.
Thanks
