Correct Answer: CO ₂ + H ₂ O + heat and light

Solution : The correct option is CO ₂ + H ₂ O + heat and light .

When Ethanol (CH ₃ CH ₂ OH) reacts with oxygen (O ₂ ) in the presence of a suitable catalyst, combustion occurs, leading to the formation of carbon dioxide (CO ₂ ) and water (H ₂ O). The balanced chemical equation for the combustion of ethanol is as follows:

C ₂ H ₅ OH + 3 O ₂ → 2 CO ₂ + 3 H ₂ O (l)

This equation indicates that one molecule of ethanol reacts with three molecules of oxygen to produce two molecules of carbon dioxide and three molecules of water.
