Which of the following compounds undergoes an S_N1 reaction mechanism?

Step 1: Understand what an S_N1 reaction is. It is a type of nucleophilic substitution reaction that involves two main steps.
Step 2: Identify the first step of the S_N1 reaction, which is the formation of a carbocation. This happens when a leaving group departs from the substrate.
Step 3: Recognize that the stability of the carbocation is crucial. Tertiary carbocations (attached to three carbon atoms) are more stable than secondary or primary carbocations.
Step 4: Look at the compounds given in the question. Determine which compound can form a tertiary carbocation when the leaving group leaves.
Step 5: Conclude that the compound that can form a stable tertiary carbocation will undergo an S_N1 reaction mechanism.
