Does the amount of energy affect the dissociation of methane

Click For Summary

Discussion Overview

The discussion centers on the relationship between energy levels and the dissociation of methane into different species, specifically free radicals and ions. Participants explore how varying amounts of energy may influence the type of dissociation that occurs, considering both theoretical and practical implications.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • Some participants propose that different amounts of energy could lead to different dissociation products of methane, such as free radicals versus ions.
  • One participant suggests that if more energy is absorbed, the molecule may dissociate into ions, while less energy would lead to dissociation into free radicals.
  • Another participant expresses uncertainty, indicating that the specific reaction conditions would determine the energy requirements for dissociation.
  • A participant assumes that in the gas phase, dissociation into ions generally requires more energy due to the need to overcome attractive forces between charged particles.

Areas of Agreement / Disagreement

Participants do not reach a consensus, as there are multiple competing views regarding the energy requirements for different dissociation pathways of methane.

Contextual Notes

Limitations include assumptions about reaction conditions, the specific energy thresholds for different dissociation pathways, and the lack of detailed mathematical analysis regarding energy levels.

I hear that methane is known dissociate into free radicals and sometimes into ions (carbocation and hydrogen proton). Is it different amounts energy responsible for the same molecule (methane) to undergoing different kinds of dissociation?

Yes.

Yes.
Could you explain how?

You've already answered your own question.

Does this mean that if energy absorbed is more the molecule will dissociate into ions and if it is less molecule will dissociate into free radicals?
 
I would assume in the gas phase dissociation into ions always requires more energy, as you have to move attracting charges away.
