What is the difference between electronic geometry and molecular shape? They differ as molecular geometry refers to the arrangement of atoms in a molecule around the central atom(s), while electron geometry refers to the arrangement of electron density around the central atom(s). The definitions of molecular geometry and electronic geometry are different. A represents the central atom, each X represents an atom bonded to A (or bond pair), and each E represents a lone pair on the central atom.īelow is the table of molecular geometries, arranged for different electron pairs:Īre electron geometry and molecular geometry definitions the same?

AXE MethodĪXE method is an efficient tabular idea to represent molecular geometries. Various techniques to determine molecular geometry include Raman spectroscopy, infrared spectroscopy, and microwave spectroscopy. It influences a substance’s properties such as its reactivity, color, polarity, magnetism, biological activity, and phase of matter. Molecular geometry includes geometrical parameters such as bond lengths, bond angles, and torsional angles that help determine the position of atoms as well as a molecule’s general shape.

The shape of a molecule is determined by the bonded atom, although this does not mean the shape itself is unaffected by the presence (repulsion) of lone pair(s).
