Verified step by step guidance1
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. Addition reactions involve adding atoms or groups to a molecule without replacing any existing groups. E1 and E2 reactions are elimination reactions, where a molecule loses atoms or groups, typically forming a double bond.
Recognize that the SN1 reaction is the only option among the given choices that involves nucleophilic substitution. The key feature is the substitution of a leaving group by a nucleophile, which is not present in addition or elimination reactions.
Conclude that the SN1 reaction is an example of a nucleophilic substitution reaction, as it fits the criteria of replacing a leaving group with a nucleophile, unlike the other reactions listed.
