A$$-4$$
B$$0$$
C$$+4$$
D$$+6$$
Correct Answer

Solution

A compound of $$Xe$$ and $$F$$ is found to have $$53.5$$% of $$Xe$$.
100 g of this compound will have $$53.5$$ g of Xe and $$46.5$$ g of F.
The atomic masses of Xe and F are 131.2 g/mol and 19 g/mol respectively.
The number of moles of $$Xe =\cfrac { 53.5 }{ 131.2 } =0.4$$
The number of moles of $$F=\cfrac { 46.5 }{ 19 } =2.4$$
The mole ratio $$Xe:F=0.4 : 2.4=1 : 6$$
Molecular formula of the compound is $$Xe{F}_{6}$$

Let n be the oxidation number of $$Xe$$ in $$Xe{F}_{6}$$
The oxidation number of F is $$-1$$
$$n+6(-1)=0$$
$$n-6=0$$
$$n=6$$
The oxidation number of $$Xe$$ in $$Xe{F}_{6}$$ is $$+6$$
