Final answer:
The main product of the SN1 hydrolysis of 2-bromo-3-methyl butane is 2-methyl-2-butanol due to the formation of a more stable tertiary carbocation intermediate.
Step-by-step explanation:
The hydrolysis of 2-bromo-3-methyl butane by SN1 mechanism leads to the formation of a carbocation intermediate. As the carbocation forms, it seeks to attain the most stable configuration, which in this case is the more substituted carbocation. In an SN1 reaction, the carbocation can rearrange to form a more stable carbocation if possible. For this compound, a hydride shift can occur from the adjacent carbon to form a more stable tertiary carbocation. Once the stable carbocation is formed, water, which acts as a nucleophile, can attack the carbocation to form the alcohol.
Therefore, the main product of the hydrolysis of 2-bromo-3-methyl butane will be 2-methyl-2-butanol. This option corresponds to Option B: 2-Methyl-2-butanol.
