The reaction between 2-methyl-2-pentanol and hbr to yield 2-bromo-2-methylpentane is probably: an sn2-type reaction involving the protonated alcohol as the substrate. an epoxidation reaction. an sn1-type reaction involving the protonated alcohol as the substrate. an e2-type reaction involving the protonated alcohol as the substrate. an e1-type reaction involving the protonated alcohol as the substrate.

The correct answer is an type reaction involving the protonated alcohol as the substrate.

Explanation: reactions are a type of nucleophilic reactions. These reactions are considered as the unimolecular reactions in which only 1 component is used to determine the rate of the reaction.

This reactions involved the generation of a carbocation as an intermediate.

For the reaction of 2-methyl-2-pentanol and HBr, the intermediate formed is  protonated alcohol which yields the product 2-bromo-2-methylpentane.

Reaction is attached in the image below.

the answer is 303.15 or 303
