The mistake in the mechanism of indicated reaction should be pointed out and correction should be proposed. Concept introduction: Carbocation formation is relatively slower than acid-base reactions. Carbocations generated from alkyl halides have two fates; they can be either trapped by nucleophiles to give substitution product or may deprotonate to yield a small amount of alkene . Unimolecular 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 a 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:
