Which of the following reactions is an example of a nucleophilic substitution reaction?
A
SN1 reaction
B
E2 reaction
C
Diels-Alder reaction
D
E1 reaction
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 two main types are SN1 and SN2 reactions.
Identify the characteristics of an SN1 reaction: It is a two-step process where the leaving group departs first, forming a carbocation intermediate, followed by the nucleophile attacking the carbocation.
Review the characteristics of the other reactions: E2 and E1 are elimination reactions, where a base removes a proton, resulting in the formation of a double bond. The Diels-Alder reaction is a cycloaddition reaction, forming a six-membered ring.
Compare the given reactions: Recognize that the SN1 reaction fits the definition of a nucleophilic substitution reaction, as it involves a nucleophile replacing a leaving group.
Conclude that the SN1 reaction is the correct example of a nucleophilic substitution reaction among the options provided.
