Question

The average oxidation number of $Br$ in $B{r}_3{O}_8$ is

• A. $\frac{16}{6}$
• B. $\frac{32}{6}$
• C. $\frac{16}{3}$
• D. Both (b) and (c)

Answer 1

Answer: (C)

Let the oxidation number of $Br$ is $x$.

$3x+(-16)=0$
$\Rightarrow x=\frac{16}{3}$
Thus, the average oxidation number of $Br$ in $B{r}_3{O}_8$ is $\frac{16}{3}$.
