In molecular orbital theory, how are electrons described?

• Fixed in specific positions

• Orbiting in circular paths

• Delocalized over the entire molecule

• Confined to individual atoms

Why is it challenging to solve the Schrödinger equation for entire molecules?

• It requires complex chemical reactions

• It only applies to single atoms

• It is a second-order differential equation

• It does not account for electron spin

• LCAO combines orbitals from all atoms in a molecule

• LCAO uses only one atom's orbitals

What is the main difference between valence bond theory and molecular orbital theory?

• Molecular orbital theory uses LCAO for all atoms in a molecule

• Molecular orbital theory confines electrons to atoms

• Valence bond theory explains electron delocalization

• Valence bond theory uses LCAO
