Question

Iodine reacts with concentrated $HN{O}_3$ to yield $Y$ along with other products. The oxidation state of iodine in $Y$ is:

• A. $5$
• B. $3$
• C. $1$
• D. $7$

Answer 1

The correct option is A $5$

Here the product $Y$ is $HI{O}_3$.

In $HI{O}_3$, oxidation state of iodine is $+5$.

Hence, the correct option is $\text{A}$
