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.

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
