Question:

Which one of the following reactions of Xenon compounds is not feasible?

2XeF2+2H2O→2Xe+4HF+O2

3XeF4+6H2O→2Xe+XeO3+12HF+1.5O2

XeF6+RbF→Rb[XeF7]

XeO3+6HF→XeF6+3H2O

Solution:

HF is the strong reducing agent and hence, it will definitely reduce xenon's oxidation state. But in the option (A), the oxidation number of xenon is unchanged and hence, it is not feasible.
