Which of the following types of reactions is an example of a nucleophilic substitution reaction?
A
Hydrogenation
B
E2 reaction
C
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. 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.
Compare the given options: Hydrogenation is an addition reaction, E2 is an elimination reaction, and E1 is also an elimination reaction. None of these involve a nucleophile replacing a leaving group.
Recognize that the SN1 reaction fits the definition of a nucleophilic substitution reaction, as it involves a nucleophile substituting a leaving group.
Conclude that among the given options, the SN1 reaction is the correct example of a nucleophilic substitution reaction.
