The reaction follows an \( S_N1 \) pathway, initiating with the departure of the chlorine atom and subsequent carbocation generation.
A 1,2-hydride shift then transpires to enhance carbocation stability, yielding a more robust tertiary carbocation intermediate.
Finally, nucleophilic attack by a hydroxide ion (\( \text{OH}^- \)) results in the formation of the primary product:
This principal product is a tertiary alcohol.
