Which of the following reactions is an example of a nucleophilic substitution reaction?
A
E2 reaction
B
Hydrogenation reaction
C
E1 reaction
D
SN1 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 reactions: E2, Hydrogenation, E1, and SN1. E2 and E1 are elimination reactions, not substitution. Hydrogenation involves the addition of hydrogen, not substitution.
Recognize that SN1 is the only reaction among the options that fits the definition of a nucleophilic substitution reaction, as it involves the substitution of a leaving group by a nucleophile.
Conclude that the SN1 reaction is the correct example of a nucleophilic substitution reaction from the given options.
