Valence Bond (VB) theory explains how chemical bonds form through the overlap of atomic orbitals, where electron pairs are shared between atoms. The key concepts include: Atomic Orbital Overlap: Bonds form when atomic orbitals from...

Bond Angle Distortion: Lone pairs reduce bond angles between bonding pairs. For example, in a molecule like NH₃ (ammonia), the ideal tetrahedral angle of 109.5° is compressed to around 107° due to the presence of a lone pair on nitrogen....
