Valence Bond theory

Question 1

Valence bond theory

Answer 1

Electrons reside in quantum-mechanical orbitals. Some being hybridized atomic orbitals. Which is two or more standard orbitals combined. Bigger overlap the lower the energy

Question 2

Interaction energy

Answer 2

Distance between two bonding atom: if lowered bond forms

Question 3

Electrons paring

Answer 3

In valence bond theory electrons will overlap half filled orbitals or less commonly completely filled orbitals

Question 4

Geometry of molecule

Answer 4

Depends on overlapping shells orbitals

Question 5

Hybridization

Answer 5

Different from atoms orbitals, form from molecules forming. minimize molecule energy, but requires a lot of energy. Usually occurs on central atom, because they are most likely to bond

Question 6

Calculating hybridization

Answer 6

• atomic orbitals = hybrid formed
• combinations of orbitals = shape and energy
• hybridization always forms the lowest energy
