$F_2O$

Vedclass · Answer

(A) Oxygen is the second most electronegative element after fluorine. Therefore,it usually exhibits a negative oxidation state.In $F_2O$,fluorine is the most electronegative element and has an oxidation state of $-1$. Let the oxidation state of oxygen be $x$. Then,$x + 2(-1) = 0$,which gives $x = +2$.In $Cl_2O$,chlorine is less electronegative than oxygen,so oxygen has an oxidation state of $-2$.In $Na_2O_2$ (sodium peroxide),oxygen is in the peroxide state with an oxidation state of $-1$.In $Na_2O$ (sodium oxide),oxygen has an oxidation state of $-2$.

In which of the following,oxygen has $+2$ oxidation number?
