Identify possible products of dehydrohalogenation of trans-1-bromo-2-methylcyclohexane

The answer for this problem is only 3-methylcyclohex-1-ene. When trans- 1- bromo- 2-methylcyclohexane is exposed to dehydrohalogenation, the formation formed is 3-methyl-1-cyclohexene. The explanation for the changed products of these two reactions can be explained by sketching suitable reaction mechanisms.

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.
