The outcome of the indicated reaction should be predicted and explained mechanistically. Concept introduction: Unimolecuar substitution or S N 1 proceeds via a two-step mechanism. The first slow step that determines the rate is the removal of the leaving group from the substrate haloalkane and generates a carbocation. Since the rate is only governed by substrate alone and no other nucleophile or solvent it is termed as an unimolecular substitution. The final step is the attack of the nucleophile on carbocation generated and the formation of racemic products. A general S N 1 reaction mechanistic pathway is illustrated below:
