Question

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.

Answer 1

Answer: The correct answer is an
`S_N1` type reaction involving the protonated alcohol as the substrate.

Step-by-step explanation:
`S_N1` 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.
