SN1 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. They are characterized by the presence of a nucleophile, a substrate, and a leaving group.
Identify the SN1 reaction as a type of nucleophilic substitution. The SN1 reaction is a unimolecular nucleophilic substitution reaction where the rate-determining step involves the formation of a carbocation intermediate.
Compare the SN1 reaction with other reactions listed. The Diels-Alder reaction is a cycloaddition reaction, not a nucleophilic substitution. The E2 reaction is a bimolecular elimination reaction, and the E1 reaction is a unimolecular elimination reaction.
Recognize the key features of the SN1 reaction: it typically occurs in two steps, starting with the formation of a carbocation intermediate, followed by the attack of the nucleophile.
Conclude that the SN1 reaction is the correct example of a nucleophilic substitution reaction among the options provided.
