Key Concepts

Hybridization

Hybridization is a concept in molecular orbital theory that explains how atomic orbitals mix to form new, equivalent hybrid orbitals used to form sigma bonds. It provides a framework for understanding the arrangement of electron density in a molecule and helps predict molecular geometry and bond angles.

Valence Shell Electron Pair Repulsion (VSEPR) Theory

VSEPR theory is used to predict the geometry of a molecule based on the repulsions between electron domains, which include bonding pairs and, in some cases, lone pairs. This theory aids in deducing the hybridization state of an atom by considering the number of electron groups surrounding it.

Steric Number

The steric number, which is the sum of atoms bonded to a central atom plus the number of lone pairs on that atom, is a critical determinant of the hybridization state. For instance, a steric number of 3 typically suggests sp² hybridization, whereas a steric number of 4 generally indicates sp³ hybridization.

Resonance and Electron Delocalization

Resonance and electron delocalization can influence the effective hybridization of an atom by distributing electron density over multiple structures. This delocalization may lead to adjustments in orbital hybridization as atoms optimize their bonding interactions under conditions of extended electron sharing.
