Verified step by step guidance1
Understand the concept of a nucleophilic substitution reaction: In organic chemistry, a nucleophilic substitution reaction involves the replacement of a leaving group by a nucleophile. This can occur via two main mechanisms: SN1 and SN2.
Identify the characteristics of an SN1 reaction: The SN1 reaction is a two-step process where the leaving group departs first, forming a carbocation intermediate. This is followed by the nucleophile attacking the carbocation.
Differentiate between the given reaction types: Addition reactions involve adding atoms or groups to a molecule without removing any atoms. E1 and E2 reactions are elimination reactions, where atoms are removed to form a double bond.
Recognize that the SN1 reaction is a nucleophilic substitution: Among the options provided, the SN1 reaction is the only one that fits the definition of a nucleophilic substitution reaction.
Conclude that the SN1 reaction is the correct example of a nucleophilic substitution reaction in the given list.
