CHEMISTRY COMMUNITY

I get that ligands are put in order when naming a compound but why is that it is different in the chemical formula? An example of this is [FeCl(OH2)5]+ and the name is pentaaquachloridoiron(II) and i get that but why is chlorine in front of the water in the formula?

Naming is always done in an alphabetical order irrespective of the formula. It doesn't matter how we write the formula.
