STANDARD Chemistry Identification of Redox Reactions MCQ Question
Which of the following reactions is an example of a redox reaction?
XeF₆ + H₂O → XeOF₄ + 2HF
XeF₆ + 2H₂O → XeO₂F₂ + 4HF
XeF₄ + O₂F₂ → XeF₆ + O₂
XeF₂ + PF₅ → [XeF]⁺ PF₆⁻
Correct Answer
Detailed Explanation
In option C, the oxidation state of xenon changes, indicating a redox reaction. XeF₄ + O₂F₂ → XeF₆ + O₂ involves an increase in oxidation number (oxidation) and a decrease (reduction), confirming it as a redox reaction.
