Combustion Reactions in Chemistry

The video tutorial explains the reaction between benzene (C6H6) and oxygen (O2), identifying it as a combustion reaction. The instructor highlights the presence of carbon dioxide and water in the products, which are typical of combustion reactions. The video further explains the general form of combustion reactions involving hydrocarbons and oxygen, resulting in carbon dioxide and water. The tutorial concludes by reaffirming the reaction type and thanking viewers.

What are the products formed when benzene reacts with oxygen?

• Methane and oxygen

• Carbon dioxide and water

• Nitrogen and water

• Hydrogen and carbon monoxide

Which of the following indicates that a reaction is a combustion reaction?

• Presence of nitrogen in the reactants

• Formation of carbon dioxide and water

• Absence of oxygen in the reactants

• Formation of hydrogen gas

What type of reaction involves a hydrocarbon reacting with oxygen?

• Synthesis reaction

• Displacement reaction

• Decomposition reaction

• Combustion reaction

What is the general form of a combustion reaction?

• Hydrocarbon + Carbon → Carbon Dioxide + Methane

• Hydrocarbon + Oxygen → Carbon Dioxide + Water

• Hydrocarbon + Nitrogen → Ammonia + Water

• Hydrocarbon + Hydrogen → Methane + Water

Which of the following is a characteristic of an organic combustion reaction?

• Does not require oxygen

• Forms a single product

• Produces carbon dioxide and water

• Involves a metal and oxygen

What is the role of oxygen in a combustion reaction?

• It is not involved in the reaction

• It is a product of the reaction

• It acts as a catalyst

• It is a reactant that combines with a hydrocarbon
