If you performed a combustion reaction of 2-ethyl, 4-methylpropene, what products would you expect to be present?
Dafna1 [17]

The question is incomplete, here is the complete question:

If you performed a combustion reaction of 2-ethyl-1-methylpropene, what products would you expect to be present?

Answer: The products of the combustion of 2-ethyl-1-methylpropene are carbon dioxide and water.

<u>Explanation:</u>

Combustion reaction is defined as the reaction in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide gas and water molecule.

\text{Hydrocarbon}+O_2\rightarrow CO_2+H_2O

We are given a chemical compound, which is 2-ethyl-1-methylpropene. The chemical formula of this compound is C_6H_{13}

The chemical equation for the combustion of 2-ethyl-1-methylpropene follows:

4C_6H_{13}+37O_2\rightarrow 24CO_2+26H_2O

By Stoichiometry of the reaction:

4 moles of 2-ethyl-1-methylpropene reacts with 37 moles of oxygen gas to produce 24 moles of carbon dioxide and 26 moles of water

Hence, the products of the combustion of 2-ethyl-1-methylpropene are carbon dioxide and water.
