In which molecule does the chlorine have the most positive partial charge?

In the molecules of $\mathrm{HCl},\mathrm{BrCl}\text{,}$and ${\mathrm{SCl}}_2\text{, }$ the chlorine atom is electronegative. However, since oxygen in OC 2 is more electronegative than chlorine, chlorine will have a partial positive charge in ${\mathrm{OCl}}_2$.
