Understand the concept of nucleophilic substitution reactions: These reactions involve the replacement of a leaving group by a nucleophile. They are characterized by the presence of a nucleophile, a substrate with a good leaving group, and the formation of a new bond between the nucleophile and the substrate.
Identify the types of nucleophilic substitution reactions: The two main types are SN1 and SN2 reactions. SN1 reactions are unimolecular and involve a two-step mechanism, while SN2 reactions are bimolecular and involve a one-step mechanism.
Analyze the given options: Hydrogenation is an addition reaction, not a substitution. E2 and E1 are elimination reactions, which involve the removal of atoms or groups from a molecule, not substitution.
Focus on the SN1 reaction: This is a nucleophilic substitution reaction where the rate-determining step involves the formation of a carbocation intermediate. The nucleophile then attacks the carbocation to form the product.
Conclude that the SN1 reaction is the correct example of a nucleophilic substitution reaction among the given options, as it involves the substitution of a leaving group by a nucleophile.
