# Is SiCl4 square planar or tetrahedral?

Nov 18, 2015

${\text{SiCl}}_{4}$ is tetrahedral.

#### Explanation:

The Lewis structure of ${\text{SiCl}}_{4}$ is

This is an ${\text{AX}}_{4}$-type molecule, with four $\text{Si-Cl}$ bonds.

According to VSEPR theory, these bonds must be pointing towards the corners of a regular tetrahedron.

So ${\text{SiCl}}_{4}$ has a tetrahedral shape.
