To determine the correct order of acidity among the given oxyacids of chlorine, we need to understand the relationship between the number of oxygen atoms and acidity.$\\$The acidity of oxyacids generally increases with the increase in the number of oxygen atoms attached to the central atom. This is because more oxygen atoms lead to greater stabilization of the conjugate base through resonance and inductive effects.$\\$Let's analyze the given oxyacids:$\\$• $$HClO (hypochlorous acid)$\\$• $$HClO$_2$
