The source of chemical bonding

Area of Science:

• Quantum chemistry
• Theoretical chemistry
• Chemical bonding

Background:

• Tracing the historical development of quantum mechanics in chemistry.
• Examining the evolution of the covalent bond concept.
• Reviewing foundational work by Heitler and London on shared electron pairs.

Observation:

• Molecular orbital theory presented a challenge to classical bonding concepts.
• The role of electron delocalization in chemical bonding is re-evaluated.
• The existence of the chemical bond remains a subject of discussion.

Findings:

• Quantum mechanics provides a framework for understanding the covalent bond.
• The implications of electron delocalization are not as disruptive to classical models as once thought.
• Recent research addresses the causal aspects and forces within covalent bonds.

Implications:

• Provides a nuanced view of the covalent bond, integrating quantum mechanical principles.
• Offers clarity on the nature of chemical bonding forces.
• Contributes to ongoing theoretical discussions in chemical bonding theory.
