Chemistry Question on Chemical Reactions

Question

Consider the above chemical reaction. Product "A" is:

Answer 1

The reaction proceeds via an $S_N1$ mechanism where the chlorine group leaves, forming a carbocation.

After the formation of the carbocation, a 1,2-hydride shift occurs to stabilize the carbocation, resulting in a more stable tertiary carbocation.

Subsequent attack by hydroxide ion ( $\text{OH}^-$ ) leads to the formation of the major product:
Sol Figure
The major product is a tertiary alcohol.
