Chapter 20, Problem 77A

Interpretation Introduction

Interpretation: The balanced chemical equation of the reaction between fluorine and oxygen thereby resulting in the formation of fluorine monoxide formation is to be determined.

Concept introduction: The reactions which involve oxidation and reduction are found to be the redox reaction. The element that is having high electronegativity values will undergo reduction and the ones with fewer electronegativity values will undergo oxidation.

Answer to Problem 77A

The balanced chemical equation of the reaction between $F_2$ and $O_2$ is,

  $2F_2+O_2\to 2F_{2}O$

Explanation of Solution

Among $F_2$ and $O_2$ , the more electronegative one is F. So, it will undergo reduction faster than oxygen. That is the element that is losing electrons in the reaction between $F_2$ and $O_2$ is $O_2$ .

Oxidation: $O_2\to 2O+2e^{-}$

Reduction: $F_2+2e^{-}\to 2F^{-}$

The balanced chemical equation of the reaction between $F_2$ and $O_2$ is,

  $2F_2+O_2\to 2F_{2}O$
