Benzene forms the electron shell configuration of two rings of

Click For Summary

Discussion Overview

The discussion centers on the electron shell configuration of benzene and the implications of running an electron beam through the molecule. Participants explore the behavior of electrons in relation to magnetic fields and the structural characteristics of benzene's electron arrangement.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions whether an electron beam passing through benzene would cause electrons to flow systematically in the ring structure.
  • Another participant expresses uncertainty about the stability of electron flow, noting that the ring structure of benzene is not a perfect ring but suggests that electron trends could still be influenced.
  • A later reply identifies the phenomenon as a well-known occurrence referred to as aromatic ring current, implying that this behavior is recognized in the field.
  • There is a suggestion that reversing the flow of electrons could theoretically apply an opposing force to all electrons in the system.
  • One participant clarifies that the two rings of delocalized orbitals in benzene are not separate entities, arguing that the depiction of the delocalized orbital may be exaggerated and that the rings meet at each carbon site.

Areas of Agreement / Disagreement

Participants express differing views on the stability and behavior of electrons in benzene, with some supporting the idea of systematic flow while others raise concerns about the structural accuracy of the model. The discussion remains unresolved regarding the implications of electron flow and the nature of the orbital structure.

Contextual Notes

Participants note limitations in the understanding of electron flow stability and the accuracy of the visual representation of benzene's electron configuration. There are unresolved questions about the effects of opposing electron beams on the system.

Benzene forms the electron shell configuration of two rings of electrons, parallel to the molecule, shown here http://upload.wikimedia.org/wikiped...e_Orbitals.svg/750px-Benzene_Orbitals.svg.png

so my question is, if an electron beam is run through the center of the benzene, would the resultant magnetic field cause the electrons to flow in a systematic way in the ring?

This actually seems like a viable theory at first, although I am unsure how the electrons would flow stability wise, as the ring structure you mention is not in fact a perfect ring. However you could influence the electron trend.

An interesting question to pose is, if you go the electrons to flow in a specific way, what would happen if the electron beam stopped an a second beam going the opposite way through the benzene molecule started. Theoretically the exact opposite force would be applied to the electrons.
 


It's not only a viable theory, but a well-known phenomenon called http://en.wikipedia.org/wiki/Aromatic_ring_current" .

Then reversal of the flow could theoretically apply exact opposing force to all of the electrons.
 


The two rings of a delocalized orbital are not separate entities, just as two lobes of a single p-orbital are not separate. I think the figure describing the delocalized orbital is a little exaggerated. Two rings should meet at each carbon site in the same way as the lobes of their constituent p_z orbitals do.
