Verified step by step guidance

Understand the concept of nucleophilic substitution reactions. These reactions involve the replacement of a leaving group by a nucleophile. The two main types are SN1 and SN2 reactions.

Identify the characteristics of an SN1 reaction. SN1 reactions are unimolecular nucleophilic substitution reactions where the rate-determining step involves the formation of a carbocation intermediate.

Compare the given reactions: Hydrogenation, SN1, E1, and E2. Hydrogenation involves the addition of hydrogen, E1 and E2 are elimination reactions, while SN1 is a nucleophilic substitution reaction.

Recognize that SN1 reactions are characterized by a two-step mechanism: first, the leaving group departs, forming a carbocation, and second, the nucleophile attacks the carbocation.

Conclude that among the options provided, the SN1 reaction is the example of a nucleophilic substitution reaction, as it involves the substitution of a leaving group by a nucleophile.
