Valence Bond Theory: A Journey into Chemical Bonding

The video tutorial explains the valence bond theory proposed by Hitler and London, focusing on the concept of atomic orbital overlap in bond formation. It describes how half-filled atomic orbitals overlap to form covalent bonds, using hydrogen atoms as an example. The tutorial highlights the importance of orbital overlap in reducing energy and forming stable molecules. It also explains the formation of a sigma bond in a hydrogen molecule through axial overlap of atomic orbitals, emphasizing the role of electron cloud concentration in molecular stability.

What is the significance of the overlap of atomic orbitals in the formation of a covalent bond?

How does the extent of overlapping of atomic orbitals affect the strength of a bond?

Explain how the shared electron pair contributes to the stability of a molecule.

Describe the process of hydrogen molecule formation using valence bond theory.

What is a Sigma bond and how is it formed between two hydrogen atoms?
