Iodine reacts with hypo to give:

If, ${\mathrm{Y}}_2$ in given reaction is ${\mathrm{Cl}}_2$ then $“\mathrm{X}"$ can be:

${\mathrm{Y}}_2+2{\mathrm{X}}^{-} \left(\mathrm{aq}\right)⟶2{\mathrm{Y}}^{-} \left(\mathrm{aq}\right)+{\mathrm{X}}_2$

Give the appropriate reason for the following statement:

Metal fluorides are more ionic than metal chlorides.
