Question

Using Valence shell Electron Pair Repulson (VSEPR) theory, predict the molecular geometry of Ammonia, NH3

Answer 1

Ammonia has 4 regions of electron density around the central nitrogen atom (3 bonds and one lone pair). These are arranged in a tetrahedral shape. The resulting molecular shape is trigonal pyramidal with H-N-H angles of 106.7°.
