AIIMS 2019 Chemistry Alkynes MCQ Question
The complete reaction is shown below.
(A)
(B)
(C)
(D)
Correct Answer
Detailed Explanation
Option B 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 equal on both sides of the equation.
Options A, C, and D may misrepresent the ratios of the reactants and products or fail to include all necessary components, leading to an imbalance that violates fundamental chemical principles. For instance, if any of these options omit H₂O or CO₂, they do not accurately reflect the complete combustion process.
