AIIMS 2018 Chemistry Reaction Mechanisms MCQ Question

Option C is correct because it accurately represents the stoichiometry of the reaction, balancing the reactants and products according to the law of conservation of mass. In this reaction, the formation of water (H₂O) and carbon dioxide (CO₂) from the combustion of a hydrocarbon is correctly depicted, ensuring that the number of atoms of each element is the same on both sides of the equation. Other options are incorrect as they either misrepresent the products formed, fail to balance the equation, or omit essential reactants, leading to an inaccurate depiction of the chemical process. Understanding the principles of balancing chemical equations is crucial for predicting the outcomes of reactions in stoichiometry.
