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 nucleophile is an electron-rich species that donates a pair of electrons to form a new bond.

Identify the characteristics of an SN1 reaction. SN1 stands for 'Substitution Nucleophilic Unimolecular'. This type of reaction involves two main steps: the formation of a carbocation intermediate and the subsequent attack by the nucleophile.

Compare the SN1 reaction with other types of reactions listed. E1 and E2 reactions are elimination reactions, not substitution reactions. The Diels-Alder reaction is a cycloaddition reaction, which involves the formation of a ring structure, not a substitution.

Recognize that the SN1 reaction is a nucleophilic substitution reaction because it involves the substitution of a leaving group by a nucleophile, following the formation of a carbocation.

Conclude that among the options given, the SN1 reaction is the correct example of a nucleophilic substitution reaction in organic chemistry.
