Which of the following equations is not shown by the appropriate halogen ?

$\begin{array}{1 1}F_2+2OH^-\rightarrow 2F^-+H_2O+OF_2\\2F_2+4OH^-(conc)\quad\underrightarrow{\text{hot}}\quad 4F^-+2H_2O+O_2\\X_2+2OH^-(conc)\quad\underrightarrow{\text{hot}}\quad H_2O+X^-+XO^-;\text{where X is Cl,Br and I}\\Xe+F_2\quad \underrightarrow{\text{light}} \quad XeF_2\end{array} $

Can you answer this question?

Answer : $X_2+2OH^-(conc)\quad\underrightarrow{\text{hot}}\quad H_2O+X^-+XO^-$;where X is Cl,Br and I
The reaction of halogens(except $F_2$) with hot and concentrated alkali is
$3X_2+6OH^-(conc)\quad \underrightarrow {\text{hot}} \quad 3H_2O+5X^-+XO_3^-$
