Draw the Lewis structure of SiH{eq}_4{/eq} including lone pairs. Do not include the formal charges.

Question:

Lewis Structure of Molecules:

The Lewis structure of a molecule is its simple two-dimensional representation wherein the bond pairs are represented by dots or straight lines and the lone pairs by two dots over the atoms.

Geometry of Molecules:

• It is important to be able to draw the structure of a molecule because it can give information on the geometry around the atoms within the molecule.
• Molecular geometry influences properties such as freezing and boiling point because the geometry affects the extent of intermolecular forces which act between molecules.
• Molecular geometry also influences the rate of reactions in which a chemical participates because reactions can proceed more slowly if the space around the atom or specific bond is hindered by other atoms in the molecule.

Answer and Explanation: 1

The Lewis structure of SiH{eq}_{4}{/eq} is given below :

This shape in three dimensions is denoted as tetrahedral (a tetrahedron).
