What's New in V

2.0.0

November 2, 2025

V-SEPR – A tool that allows you to model the geometry of molecules based on VSEPR theory (3D), now with the added ability to build Lewis structures directly within the application (2D) — a new feature. Build and observe to become familiar with Lewis structures, repulsion shapes, molecular geometry, and bond angles. You can now navigate between 3D and 2D representations. We look forward to your feedback!

User reviews

Scientifically incorrect

A good visualiser for 3D molecules, fine for showing bond angles - UNLESS the molecule contains lone pairs. Lone pairs are treated as bonded regions, meaning the bond angles for pyramidal and non-linear molecules are incorrect.

it’s really easy to use and it helps me so much

I do recommend it
