The correct order of the compounds in terms of increasing oxidation state of chlorine is:
Cl2 < NaClO4 < Cl2O7 < HClO4
This is because the oxidation state of chlorine in these compounds is as follows:
Cl2: 0NaClO4: +7Cl2O7: +7HClO4: +7
Therefore, the correct order is Cl2 < NaClO4 < Cl2O7 < HClO4.
The correct order of the compounds in terms of increasing oxidation state of chlorine is:
Cl2 < NaClO4 < Cl2O7 < HClO4
This is because the oxidation state of chlorine in these compounds is as follows:
Cl2: 0
NaClO4: +7
Cl2O7: +7
HClO4: +7
Therefore, the correct order is Cl2 < NaClO4 < Cl2O7 < HClO4.
