Silicon Tetrachloride overview

The stored Lewis connectivity is SiCl₄. Silicon forms four single bonds and each terminal chlorine retains three lone pairs.

How to draw SiCl₄

  1. Count 32 valence electrons. Include charge adjustments before drawing.
  2. Use the reviewed connectivity SiCl₄. Do not infer a different isomer from the formula alone.
  3. Place the required single, double or multiple bonds. Keep a running electron total.
  4. Complete terminal valence shells and add lone pairs or formal charges. Silicon forms four single bonds and each terminal chlorine retains three lone pairs.
  5. Verify the total electron count and geometry. The reviewed geometry is Tetrahedral, 109.5°.

Why this example matters

Silicon forms four single bonds and each terminal chlorine retains three lone pairs.

Scope and model limits

A flat Lewis drawing represents tetrahedral connectivity; it is not the molecular shape.

Common mistakes

  • Leaving chlorine without three lone pairs
  • Drawing Si=Cl multiple bonds
  • Calling the molecule planar
