WebRather, one determines the geometry by an independent mean (e.g. quantum chemical calculations, gas phase diffraction), deduces the bond angles (and bond lengths) from the geometry and then derives a hybridisation. In short: hybridisation follows geometry, not the other way around. Share Improve this answer Follow edited Sep 13, 2024 at 9:24 WebVSEPR Theory: According to VSEPR theory, the molecular geometries and bond angles are decided by the electron groups present on the central atom.The geometry can be tetrahedral, seesaw, t-shaped, trigonal pyramidal, square pyramidal, and octahedral.
