Indicate whether the specified alkyl halides will form primarily substitution products, only elimination products, both substitution and elimination products, or no products when they react with sodium methoxide. 1-bromobutane 1-bromo-2-methylpropane 2-bromobutane 2-bromo-2-methylpropane

Reactants are more stable in the given reaction.

Explanation:

When heat is absorbed by reactant species from the surrounding then it is known as an endothermic reaction. In an endothermic reaction, energy of reactants is less than the energy of products.

It is known that when energy of a substance is more then it is considered as unstable and when energy of a substance is less then is is considered as stable.

So, when is positive then it means heat is absorbed by the system. And when   is negative then it means heat is released by the system.

Therefore, we can conclude that in the given reaction reactants are more stable than products.
