$X_2$ is used in the refining of $Ti$ metal by the van Arkel method. $Y_2$ does not liberate $O_2$ from water and does not form $HY$ and $HOY$ with water. $X_2$ and $Y_2$ are respectively:

The correct order of the thermal stability of hydrogen halides $(HX)$ is:

$Fluorine$ does not form positive oxidation states because

$Br_2 + F_2$ (Excess) $\xrightarrow{\Delta} BrF_5$. When $F_2$ is diluted with $N_2$ gas,then the product of $Br$ would be:
