Molecular Shapes; the VSEPR Model (Sections)
Give the electron-domain and molecular geometries for the following molecules and ions: (a) HCN, (b) SO32 -, (c) SF4, (d) PF6-, (e) NH3Cl+, (f) N3-.
Step 1 of 7
For a given covalent molecule, the shape can be predicted by electron domain geometry and the lone pair of electrons on the central atom. The electrons domain geometry represents the number of electron pairs around the central atom.
Molecular geometry gives the actual shape of the molecule, and sometimes it deviates from electron geometry.
