Tetrahedral: 0 lone pairs, 4 bonding locations




This is an example of a tetrahedral molecule that contains no lone pairs. This is a silicon chloride molecule, SiCl4, which has 32 valence electrons to use for the lewis dot structure. When the lewis dot structure is drawn there are four bonding locations and no lone pairs on the central atom. This type of configuration would give you a tetrahedral geometry. This geometry an angle between the atoms which is 109.5° degrees all around. Quiz Yourself: CH4,CCl4, SiF4, SnCl4
