Homework Answers
1.
SN1 reaction is Unimolecular nucleophilic substitutions
reaction.
2. In this reaction rate determining step is carbocation formation and rate is not depending on nucleophile.
3. So once carbocation form there is two sides for nucleophilic to attack and will get inversion of configuration as well as retention of configuration.
4. So in SN1 reaction will get racemic product even if we use chiraly pure starting material.
