H2S Lewis Structure

Sulfur forms two S–H single bonds and retains two lone pairs. Four electron domains surround sulfur, while the molecular shape is bent rather than linear.

H2S overview

Sulfur contributes six electrons and the two hydrogens contribute two. Two bonds use four electrons, leaving two lone pairs on sulfur.

How to draw H2S

  1. Count 8 valence electrons.
  2. Place sulfur between the two hydrogens.
  3. Draw two S–H single bonds.
  4. Place the remaining four electrons as two sulfur lone pairs.
  5. Check zero formal charges and a bent AX2E2 shape.

Geometry and angle

The stored reference angle is about 92°. Lewis structure and VSEPR explain the bent arrangement, while exact angles depend on orbital and energetic details beyond a dot diagram.

Common mistakes

  • Drawing H–S–H as a straight molecule.
  • Leaving off sulfur's two lone pairs.
  • Giving hydrogen more than two electrons.
  • Drawing S=H multiple bonds.
