In S_(N)1 reaction of (S)-2 bromobutane with water Two subsitution products are formed one has the same relative configuration as the reactant and the other has the inverted configuration. This is in most S_(N)1 reactions, the recemic product is non-50:50 mixture i.e, recemization takes place the inverted product is more than 50% . the formation of different composition of the product is due to following stpes involved in S_(N) reactions.
