The property of halogens which is not correctly matched is
$\mathrm{F}>\mathrm{Cl}>\mathrm{Br}>\mathrm{I}$ (Electronegativity)
I $>\mathrm{Br}>\mathrm{Cl}>\mathrm{F}$ (Density)
$\mathrm{F}>\mathrm{Cl}>\mathrm{Br}>$ I (Electron gain enthalpy)
$\mathrm{F}>\mathrm{Cl}>\mathrm{Br}>$ I (Ionisation enthalpy)
