VSEPR Studio

Explore VSEPR shapes by choosing an AXE formula or assigning A and X with an example molecule. The molecular geometry, bond-angle note, and polarity comment update live as the bonding and non-bonding domains change.

AXE formula
AX4

Molecular geometry: trigonal pyramidal.

Choose an AXE formula or use the X/E controls below the diagram to choose a supported VSEPR pattern.

Four bonding electron domains spread themselves out evenly, forming a tetrahedron. The expected bond angle is 109.5°. If the surrounding atoms are identical, the molecule will be non-polar.
