The given transformation involves the conversion of an alkene to an alcohol in an acidic medium. Let’s analyze the intermediates and mechanisms involved in this transformation:

1. Protonation: The first step involves the protonation of the double bond by \( \text{H}^+ \) from the acidic medium, leading to the formation of a more stable carbocation intermediate.

   This carbocation is tertiary, because the positively charged carbon is bonded to three other carbon atoms.

2. 1,2-Methide Shift: A 1,2-methide shift occurs where a methyl group with its electrons migrates from one carbon to the adjacent carbocation-bearing carbon, stabilizing it further. This step rearranges the structure to form a more stable non-classical ion.

3. Non-Classical Carbocation: The intermediate formed can be a non-classical carbocation, which is a bridged carbocation that shares positive charge over multiple centers, providing additional stabilization.

4. Nucleophilic Attack: Water, a nucleophile, attacks the carbocation, leading to the formation of the alcohol after deprotonation.

The correct intermediates and processes involved in this transformation are:

• 1,2-methide shift
• non-classical carbocation
• tertiary carbocation

These steps demonstrate the mechanistic pathway of converting the given alkene to the corresponding alcohol in acidic conditions.
