Which compound of xenon is not possible ?
  1. XeF6
  2. XeF2
  3. XeF5
  4. XeF4

A
XeF2
B
XeF5
C
XeF6
D
XeF4
Solution
Verified by Toppr

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. As a result XeF3 and XeF5 do not exist.
Hence option C is correct answer.
