The Oxidation Number of Cl in HOCl is +1.
It can be calculated as below:
Total Charge on Molecule is Zero(0). Therefore,
0 = + 1 (for Hydrogen) – 2 (for Oxygen) + X (for Chlorine)
0 = – 1 + X
X = + 1
Therefore, Oxidation Number of Chlorine in HOCl is +1.
And, it is a myth that Cl always has -1 Oxidation Number. For eg. in HClO4 Oxidation Number of Cl is +7.
