Andre is predicting the products of chemical reactions. In one reaction, a hydrocarbon is the only reactant. What is the best prediction and explanation of this reaction?

A hydrocarbon is made only of carbon and hydrogen, so with no oxygen reactant, it cannot produce carbon dioxide, water, or oxides as described in choices B and D. Some hydrocarbons can join together through polymerization to form a polymer, using the same hydrocarbon as the only reactant. Therefore, the best prediction is that a polymer forms.
