What type of reaction does cl2 h2o - Hclo have?

The reaction between Cl2 and H2O to form HOCl (also written as HClO) is a redox reaction. Chlorine in Cl2 is reduced from 0 to +1 oxidation state in HOCl, while hydrogen in H2O is oxidized from +1 to +1 oxidation state in HOCl, indicating transfer of electrons.
