Statement-I: In the reaction,

\frac{1}{2} \mathrm{O}_2+\mathrm{F}_2 \rightarrow \mathrm{OF}_2, \mathrm{~F}_2

is oxidant.

Statement-II: Fluorine cannot show positive oxidation state.

View answer and explanation

Correct option: A

Both the statements are correct

Both statements are correct. In the reaction, fluorine is more electronegative than oxygen and thus acts as an oxidant, and fluorine always has a negative oxidation state.
