Valence shell electron pair repulsion (VSEPR) theory (/ˈvɛspər, vəˈsɛpər/ VESP-ər,: 410  və-SEP-ər) is a model used in chemistry to predict the geometry...

levels of s and p orbitals. Bent's rule represents a modification of VSEPR theory for molecules of lower than ideal symmetry. For bonds with the larger...

polarity of bonds. The octet rule and VSEPR theory are examples. More sophisticated theories are valence bond theory, which includes orbital hybridization...

pair is a concept used in valence shell electron pair repulsion theory (VSEPR theory) which explains the shapes of molecules. They are also referred to...

angles in the table below are ideal angles from the simple VSEPR theory (pronounced "Vesper Theory")[citation needed], followed by the actual angle for the...

geometry are sometimes described as sp3 hybridized. The AXE method for VSEPR theory states that the classification is AX3E1. The nitrogen in ammonia has...

and methylene (CH2). This geometry is almost always consistent with VSEPR theory, which usually explains non-collinearity of atoms with a presence of...

pentagonal bipyramidal structure, with D5h symmetry, as predicted by VSEPR theory. The molecule can undergo a pseudorotational rearrangement called the...

of steric activity is that of SnCl2, which is bent in accordance with VSEPR theory. Some examples where the lone pair appears to be inactive are bismuth(III)...

the crystal, the species adopts a pyramidal structure, in accord with VSEPR theory. Bismuth chloride can be synthesized directly by passing chlorine over...
