The ionic equation for preparing hypochlorous acid by dissolving chlorine in water is Cl2+H2O=2H++ClO-+Cl-, right?

No, hypochlorite is a weak acid, written in molecular form

The following experimental designs and their corresponding ion equations are correct? Dissolving chlorine gas in water to prepare hypochlorous acid Cl2+H2O=2H++ClO-+Cl-, Why is it wrong?

Hypochloric acid is a weak electrolyte and can not be disassembled for writing. It should be written as HClO
Correct ion equation is Cl2+H2O=H++HClO+Cl-,
