Which of the following reactions is an example of a nucleophilic substitution reaction in organic chemistry?
A
Diels-Alder reaction
B
E1 reaction
C
SN1 reaction
D
E2 reaction
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. The two main types are SN1 and SN2 reactions.
Identify the characteristics of an SN1 reaction: SN1 reactions are unimolecular nucleophilic substitution reactions. They typically involve a two-step mechanism where the leaving group departs first, forming a carbocation intermediate, followed by the nucleophile attacking the carbocation.
Differentiate between the given reactions: The Diels-Alder reaction is a cycloaddition reaction, not a substitution. The E1 and E2 reactions are elimination reactions, where a molecule loses atoms or groups to form a double bond, rather than substituting one group for another.
Recognize that the SN1 reaction fits the criteria for a nucleophilic substitution reaction, as it involves the substitution of a leaving group by a nucleophile.
Conclude that among the options provided, the SN1 reaction is the correct example of a nucleophilic substitution reaction in organic chemistry.
