Verified step by step guidance

Understand the concept of a substitution reaction: In organic chemistry, a substitution reaction involves the replacement of an atom or group in a molecule with another atom or group. This is a key type of reaction where one functional group is substituted by another.

Identify the characteristics of an SN1 reaction: SN1 stands for 'nucleophilic substitution, unimolecular'. It is a type of substitution reaction where the rate-determining step involves the formation of a carbocation intermediate. The reaction typically occurs in two steps: the formation of the carbocation and the nucleophilic attack.

Compare SN1 with other types of reactions: Addition reactions involve adding atoms or groups to a molecule without removing anything. Elimination reactions involve the removal of atoms or groups from a molecule, often forming a double bond. E1 reactions are a type of elimination reaction that also involves a carbocation intermediate.

Recognize the conditions favoring SN1 reactions: SN1 reactions are favored in polar protic solvents and often occur with tertiary carbocations due to their stability. The reaction rate is dependent only on the concentration of the substrate, not the nucleophile.

Conclude why SN1 is a substitution reaction: Given the characteristics and mechanism of SN1 reactions, it is clear that they involve the substitution of one group for another, fitting the definition of a substitution reaction in organic chemistry.
