Answer:
SN1 mechanism
Step-by-step explanation:
The reaction undergoes an SN1 mechanism. SN1 mechanism is known as nucleophilic substitution reaction. A nucleophilic substitution reaction is the direct displacement of an atom or group of an atom by another atom or group. The initial phase of the nucleophilic substitution reaction follows the formation of a carbocation during the removal of the leaving group. Then the process is followed by the addition of the nucleophile to the site of the carbocation.
