Tetrahedral ..molecular geometry/inorganic chemistry
This molecule is made up of 4 equally spaced sp3 hybrid orbitals forming bond angles of 109.5o. The shape of the orbitals is tetrahedral. Since there is an atom at the end of each orbital, the shape of the molecule is also tetrahedral.
Shape: tetrahedral
Steric Number: 4
Lone Pairs: 0
Polar/NonPolar: NonPolar
Hybridization: sp3
Examples: CH4, SiH4

An example of tetrahedral electron pair geometry and molecular geometry is CH4. The carbon has 4 valence electrons and thus needs 4 more electrons from four hydrogen atoms to complete its octet. The hydrogen atoms are as far apart as possible at 109o bond angle. This is tetrahedral geometry. The molecule is three dimensional. Methane is the simplest hydrocarbon molecule present in natural gas. This molecule provides the basis for the tetrahedral geometries at each carbon in a hydrocarbon chain.
