The three-dimensional structure or arrangement of atoms in a molecule is known as molecular geometry, also known as molecular structure. Understanding a compound's molecular structure can help determine its polarity, reactivity, phase of matter, colour, magnetism, and biological activity.
We must first learn about the Lewis electron dot structure in order to determine the shapes of molecules. Although the Lewis theory does not determine molecule shapes, it is the first step in predicting molecule shapes.
The Lewis structure assists us in identifying bond pairs and lone pairs. The Lewis structure is then used to determine the molecular geometry and electron-group geometry using the valence-shell electron-pair repulsion (VSPER) theory.
To identify and have a complete description of a molecule's three-dimensional shape, we must also learn about the bond angle. Lewis Electron Dot Structures are important in determining molecule geometry because they help us identify the valence electrons.
