Can you answer this question? I know it's NOT none of the above.

The reaction of 2,2-dimethyl-1-propanol with H.Br is very slow and gives 2-bromo-2-methylbutane as the major product. Br HBr OH Give a mechanistic explanation for these observations. Check all that apply. O Stereoelectronic effects result in an anticoplanar rearrangement of the carbon skeleton. O The mechanism involves a carbocation rearrangement during which a methyl shifts. O The mechanism requires the dissociation of a poor leaving group. O Steric hindrance prevents nucleophilic attack. O The mechanism requires the development of an unstable positively charged species in the transition state. O None of the above
