Hybrid Orbitals vs. Molecular Orbitals: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on January 2, 2024
Hybrid orbitals are combinations of atomic orbitals within an atom, while molecular orbitals are formed by the overlap of atomic orbitals from different atoms in a molecule.

Key Differences

Hybrid orbitals form when atomic orbitals mix within a single atom, creating new orbitals of equal energy. Molecular orbitals, conversely, result from the overlap of atomic orbitals from different atoms in a molecule.
