JEE Main Solved Paper 2017 Question 18

Question: Which of the following reactions is an example of a redox reaction? [JEE Main Solved Paper-2017]

Options:

A) $ XeF _4+O _2F _2\to XeF _6+O _2 $

B) $ XeF _2+PF _5\to {{[XeF]}^{+}}PF _6^{-} $

C) $ XeF _6+H _2O\to XeOF _4+2HF $

D) $ XeF _6+2H _2O\to XeO _2F _2+4HF $

Show Answer

Answer:

Correct Answer: A

Solution:

  • In the reaction $ \overset{+4}{\mathop{X}},eF _4+{{\overset{+1}{\mathop{O}},}_2}F _2\to \overset{+6}{\mathop{X}},eF _6+O_2^{0} $ Xenon undergoes oxidation while oxygen undergoes reduction.
