Which statment best describes the chamces that occured in the reactant in forming the alkene product

Hello. You did not enter answer options. The options are:

a. The OH group was removed from the reactante

b. The OH group was replaced by an H atom.

c. Two atoms were removed from the reactant.

d. An H atom abd a OH group have been removed drom the reactant.

In addition, you forgot to add an image that complements the question. The image is attached below.

d. An H atom abd a OH group have been removed drom the reactant

Explanation:

As you can see in the image, the reagent is an alcohol molecule. For the transformation of the alcohol molecule into an alkene molecule, it is necessary that an intramolecular dehydration occurs, that is, it is necessary that a water molecule (two H atoms and an O atom) go out from inside the alcohol and that is exactly what happened, that is, we can say that an H atom and an OH group were removed from the reagent to form the alkene.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
