If lone pairs of electrons, electrons not bonded to other atoms, are located in the molecule, this will change the molecular geometry, not the electron geometry. If all the electron groups are bonded, with no lone pairs, then the electron geometry and molecular geometry are the same.

WebDefinition. 1 / 44. A theory that allows prediction of the shapes of molecules based on the idea that electrons- either as lone pairs or as bonding pairs- repel one another. • the preferred geometry of a molecule is the one in which the electron groups have the maximum separation (and therefore the minimum energy) possible. WebAug 19, 2024 · 2. There are three electron groups around the central atom: two double bonds and one lone pair. We initially place the groups in a trigonal planar arrangement to minimize repulsions (Table 3.2.1. 1 ). 3. With two bonding pairs and one lone pair, the structure is designated as AX 2 E.
