Which of the following oxo acids of chlorine is the best oxidisinig agent?

Options

A. HClO
B. `HClO_(2)`
C. `HClO_(3)`
D. `HClO_(4)`

Answer

A

Explanation

As the oxidation state of halogen atom increases, the halogen-xoygen bond becomes more covalent. As a result, thermal stability of the acid increases and hence, oxidizing power of oxo acid decreases. In other words, the more the oxidation state of the halogen, the lesser is the oxidizing power of its oxo acids. Thus, the oxidizing power oxo acids is in the order `HCIIO gt HCIO, gt HCIO_(3) gt HCIO_4 `. Hence, HCIO is the best oxidizing agent.
