Question

Which of the following xenon compound has the same number of lone pairs on central atom as in $I_3^{-}$?

• A. ${XeO}_4$
• B. ${XeF}_4$
• C. ${XeF}_2$
• D. ${XeO}_3$

Answer 1

Answer: (C)

${XeF}_2$

In $I_3^{-}$, there are 3 lone pair of electrons on the central atom. $Xe$ has 8 electrons in its outermost shell.In $Xe{F}_2$, two electrons are involved in the bond formation with two $F$ atoms and the remaining 6 electrons are present as 3 lone pair of electrons on the central $Xe$ atom.
