Iodine Trifluoride overview

The stored Lewis connectivity is IF₃. Three I–F bonds and two equatorial iodine lone pairs leave a T-shaped molecular geometry.

How to draw IF₃

  1. Count 28 valence electrons. Include charge adjustments before drawing.
  2. Use the reviewed connectivity IF₃. 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. Three I–F bonds and two equatorial iodine lone pairs leave a T-shaped molecular geometry.
  5. Verify the total electron count and geometry. The reviewed geometry is T-shaped AX₃E₂.

Why this example matters

Three I–F bonds and two equatorial iodine lone pairs leave a T-shaped molecular geometry.

Scope and model limits

The VSEPR drawing is an idealized molecular model; exact solid-state behavior may involve additional interactions.

Common mistakes

  • Drawing trigonal planar IF₃
  • Omitting two iodine lone pairs
  • Giving fluorine fewer than three lone pairs
