Whether or not they are in bond pairs or in lone pairs. The VSPER Theory states that electron pairs repel each other VALENCE SHELL ELECTRON PAIR REPULSION THEORY Lewis Structure we apply the Valence – shell electron pair repulsion (VSEPR)ĭraw the LEWIS ELECTRON DOT STRUCTURE of the following molecules.

LEDS helps us to identify the bond pairs and the lone pairs. LEDS play a crucial role in determining the geometry of molecules because it Whether the sample is a solid, liquid, gas, or part of a solution. The molecular geometry of a substance may be different depending on Increasing the temperature gives the molecules more energy, which can lead to The best determination of a structure is made at low temperature because Infrared (IR) spectroscopy, Raman spectroscopy,Įlectron diffraction, and microwave spectroscopy. Molecules and learn about their vibrational andĮxamples include x-ray crystallography, neutron diffraction,
