In summary, the conversation discusses the relative oxidizing strengths of ClO- and ClO4- compared to MnO4- and MnO2. The hypothesis that ClO4- should be more oxidizing than ClO- based on the comparison of MnO4- and MnO2 is questioned. The speaker suggests that the presence of multiple resonating structures and stability of ClO4- may make it less oxidizing than ClO-.

Why is ClO- more oxidising than ClO4 - ? I related this to MnO4 - and MnO2

MnO4 - is more oxidising than MnO2 so ClO4- should also be more oxidising than ClO- too

Can you give me reasons to why MnO4- is more oxidising than MnO2 but ClO4- is not a stronger oxidising agent than ClO-

Your HYPOTHESIS is wrong. Such easy comparison cannot be made ! Think about it...

Cl-O-O-O-O and Cl-O

- are bonds...

Now think which one can easily be reduced... Also same thinking should take place while analyzing manganese compounds.

This is completely off. Please don't comment on things you have no idea about.

Mn and Cl are way too different for such a simple comparison.

Ok can you give reasons of why clo- is more oxidising than clo4-
also why mno4- is more oxidising than mno2

Clo4- definitely has resonating structures and is more stable so less oxidising than clo-
 

1. What is the difference between MnO4 - and MnO2 in terms of their oxidising power?

MnO4 - is a stronger oxidising agent than MnO2. This is because MnO4 - has a higher oxidation state of +7 compared to +4 in MnO2. This higher oxidation state allows MnO4 - to gain electrons more easily, making it a stronger oxidising agent.

2. How does ClO4- compare to ClO- in terms of their oxidising power?

ClO4- is a stronger oxidising agent than ClO-. This is because ClO4- has a higher oxidation state of +7 compared to +1 in ClO-. This higher oxidation state allows ClO4- to gain electrons more easily, making it a stronger oxidising agent.

3. Which compound has a higher oxidising power, MnO4 - or ClO4-?

MnO4 - has a higher oxidising power compared to ClO4-. This is because MnO4 - has a higher oxidation state of +7 compared to +7 in ClO4-. Higher oxidation states indicate a greater ability to gain electrons, making MnO4 - a stronger oxidising agent.

4. Why do MnO4 - and ClO4- have higher oxidising powers compared to MnO2 and ClO-?

MnO4 - and ClO4- have higher oxidising powers because they have higher oxidation states. Higher oxidation states indicate a greater ability to gain electrons, which is essential for oxidising reactions. Additionally, the structure of MnO4 - and ClO4- allows for more efficient and effective electron transfer, further enhancing their oxidising powers.

5. How can the oxidising powers of MnO4 - and ClO4- be used in practical applications?

The high oxidising powers of MnO4 - and ClO4- make them useful in various practical applications. For example, they are commonly used as oxidising agents in organic synthesis reactions to convert lower oxidation state compounds into higher oxidation state compounds. They are also used in wastewater treatment plants to remove pollutants through oxidation. Additionally, they can be used as disinfectants due to their ability to kill microorganisms by oxidising their cell membranes.
