What is the oxidation number of Br in KBrO_4 ?

What is the oxidation number of Br\mathrm{Br} in KBrO4\mathrm{KBrO}_4 ?

Options

  1. A+6+6
  2. B+7+7
  3. C+5+5
  4. D+8+8

Correct answer

B. +7+7

Step-by-step solution

Let the oxidation no. of Br\mathrm{Br} be xx.  In KBrO4+1+x+4(−2)=0,−7+x=0x=+7\begin{aligned} \text{ In } \mathrm{KBrO}_4+1+x+4(-2) & =0,-7+x=0 \\ x & =+7\end{aligned}
