Which of the following reactions is an example of a nucleophilic substitution in organic chemistry?
A
E1 reaction

C
SN1 reaction
D
E2 reaction
Verified step by step guidance1
Understand the concept of nucleophilic substitution: In organic chemistry, a nucleophilic substitution reaction involves the replacement of a leaving group by a nucleophile. This process is characterized by the attack of an electron-rich nucleophile on an electron-deficient carbon atom.
Identify the types of nucleophilic substitution reactions: The two main types are SN1 and SN2 reactions. SN1 reactions are unimolecular nucleophilic substitutions, while SN2 reactions are bimolecular.
Analyze the given options: E1 and E2 reactions are elimination reactions, not substitution reactions. Hydrogenation is an addition reaction, not a substitution.
Focus on the SN1 reaction: In an SN1 reaction, the leaving group departs first, forming a carbocation intermediate. The nucleophile then attacks the carbocation, completing the substitution.
Conclude that the SN1 reaction is the correct example of a nucleophilic substitution from the given options, as it involves the replacement of a leaving group by a nucleophile.
