Polar or Non-polar?

When bond dipoles cancel

An interactive lesson with 8 steps, about 7 minutes: you predict, drag and solve, with instant feedback on every answer. It runs in your browser and needs JavaScript.

What you’ll learn

  • Net polarity = sum of bond dipoles as arrows.
  • Symmetrical shapes with identical bonds are non-polar (CO₂, BF₃, CCl₄, SF₆).
  • Lone pairs or mixed substituents usually make a molecule polar.

Steps

  1. Adding arrows
  2. Water doesn’t cancel
  3. Switch on a field
  4. Polar bonds, non-polar molecule
  5. Swap one atom
  6. Make it polar
  7. Mirror twins
  8. Sort them
