Which of the following does not exist?
Options
- AXeO 3
- BXeOF 4
- CXeF 6
- DNeF 2
Correct answer
D. NeF 2
Step-by-step solution
As Xe and Ne both are inert gases, but Xe can form compounds with Oxygen and Fluorine because of its large size. Ne is smaller in size and highly inert thus exists in atomic form only and do not form a molecule with another atom, as it is highly non-reactive. Thus, NeF 2 does not exist.
