Molecular shape & polarity

Drag to rotate. Scroll or pinch to zoom. For keyboard controls, Tab to a model. Use arrow keys to rotate, [ or ] to inspect, and Esc to clear the selection.

Bond dipoleNet dipoleArrowheads point toward the negative end. Crosses mark the positive end. Dashed guides show vector addition.
Model notes and sources

Arrow lengths illustrate the dipole moments. Atoms, bond lengths, and dipole moments are not for scale.

Shapes follow OpenStax Chemistry 2e. The SO₂ angle follows NIST experimental geometry data.

VSEPR shape chart

Each row counts the bonds and lone pairs around the central atom. A double or triple bond counts as one electron domain.

A is the central atom, X is a bonded atom, and E is a central lone pair.
