Question

The oxidation number of oxygen in $O{F}_2$ is :

• A. $+2$
• B. $-2$
• C. $+1$
• D. $-1$

Answer 1

The correct option is A $+2$

Let $x$ be the oxidation state of $O$ in $O{F}_2$.
Since the overall charge on the complex is $0$, the sum of oxidation states of all elements in it should be equal to $0$.
Therefore, $x+2(-1)=0$
or, $x=+2$.
Hence, the oxidation state of $O$ in $O{F}_2$ is $+2$.
