Is hybridization the result of electron promotion?

Click For Summary
SUMMARY

Hybridization in chemistry is fundamentally linked to the promotion of electrons, as it involves the mixing of atomic orbitals to form new hybrid orbitals. However, it is established that hybridization can occur without electron promotion, indicating that while promotion is often a contributing factor, it is not a strict requirement. This discussion highlights the complexity of hybridization as a mathematical construct that simplifies the behavior of electrons in atoms, particularly in the context of single-electron orbitals and the neglect of electron-electron interactions.

PREREQUISITES
  • Understanding of atomic orbitals and their energies
  • Familiarity with the concept of electron promotion
  • Basic knowledge of hybridization in molecular chemistry
  • Awareness of single-electron orbital theory
NEXT STEPS
  • Research the mathematical models of hybridization in quantum chemistry
  • Explore examples of hybridization without electron promotion
  • Study the implications of electron-electron interactions on hybridization
  • Learn about the different types of hybrid orbitals (sp, sp2, sp3)
USEFUL FOR

Chemistry students, educators, and researchers interested in molecular structure and bonding theories, particularly those focusing on hybridization and electron behavior in atoms.

Hi,

I wonder if hybridization occurs due to the promotion of electrons?

If the promotion would not occur, neither would hybridization?


Thanks for the help!

At its base, hybridization is a mathematical construction, where linear combinations of orbitals (of similar energies) are use to create new orbitals.

From the point of view of electrons, as it involves orbitals with different values of l, thus of different energy, it is in a sense related to the promotion of electrons.

So yes, I would say that hybridization requires promotion. But remember that it is just an approximation, based single-electron orbitals, neglecting electron-electron interactions.
 
Hi, acutally I came to the conclusion that my previous statement might not be true afterall, because I found the following example in which no promotion occurs and still hybridization takes place:

Does this mean promotion does not have to occur for hybridization?
