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. SN1 reactions are unimolecular nucleophilic substitution reactions where the rate-determining step involves the formation of a carbocation intermediate.
Compare the given reactions: SN1, E2, Diels-Alder, and E1. Note that E2 and E1 are elimination reactions, and Diels-Alder is a cycloaddition reaction, none of which involve nucleophilic substitution.
Recognize that the SN1 reaction fits the criteria for a nucleophilic substitution reaction, as it involves the substitution of a nucleophile after the formation of a carbocation.
Conclude that among the given options, the SN1 reaction is the example of a nucleophilic substitution reaction.
