Discussion Overview

The discussion centers on the comparative oxidizing power of the species ClO- versus ClO4- and MnO4- versus MnO2. Participants explore the underlying reasons for the differences in oxidizing strength among these compounds, focusing on theoretical and chemical bonding aspects.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • Some participants assert that ClO- is more oxidizing than ClO4-, paralleling the claim that MnO4- is more oxidizing than MnO2.
  • Others challenge the validity of directly comparing the oxidizing power of ClO- and ClO4-, suggesting that the differences in the chemical structures of Cl and Mn must be considered.
  • A participant emphasizes the importance of analyzing the bonding in ClO- and ClO4-, indicating that the stability of ClO4- due to resonance structures may contribute to its lower oxidizing power.
  • Some participants express skepticism about the initial hypothesis, arguing that the comparison is overly simplistic and does not account for the complexities of the compounds involved.

Areas of Agreement / Disagreement

Participants do not reach a consensus; multiple competing views remain regarding the oxidizing strengths of ClO- versus ClO4- and MnO4- versus MnO2.

Contextual Notes

The discussion reveals limitations in assumptions about the comparability of different elements and their compounds, as well as the need for deeper analysis of chemical bonding and stability factors.

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-
