- ✓$\ce{XeF_4}$
- C$\ce{XeF_5}$
- D$\ce{XeF_3}$

Answer
Correct option: B.
$\ce{XeF_4}$
$\ce{XeF_{4^-}}$ This compound is formed by xenon.
$Xe$ compounds can contain only even no. of fluorine atoms.
$Xe$ has a complete filled $5p$ configuration.
As a result when it undergoes bonding with an odd number $(3$ or $5)$ of $F$ atoms it leaves behind one unpaired electron.
This causes the molecule to become unstable.
