3D Interactive Simulation
VSEPR Theory 3D Sandbox
Build any molecule by adding bonds and lone pairs. See the 3D geometry update live, with bond angles, hybridization, and teacher insights for every shape.

🔵
Add Bonds & Lone Pairs
Use the + / − controls at the bottom of the viewport to change the number of bonds and lone pairs around the central atom.
🔄
Rotate the Molecule
Click and drag inside the 3D panel to rotate the molecule freely. Use scroll to zoom in or out.
💡
Tap the Angle Labels
Click the pink bond-angle labels to reveal a teacher's insight explaining why that specific angle exists.
JEE / NEET Relevance: VSEPR questions appear almost every year. Focus on exceptions — SnCl₂ (95°), Cl₂O (111°), NF₃ (102°), and the Bent's Rule molecules in the sp³d family.
