Valence-Shell Electron-Pair Repulsion (VSEPR) Model

Exercises

Choose a molecule or ion from the list below. (Do not click on the molecule yet!)

  1. Predict the molecular geometry using the Valence-Shell Electron-Pair Repulsion Model.
  2. Predict the ideal bond angles.
  3. Predict whether the bond angles are ideal or smaller than ideal.
  4. Predict the hybridization of the central atom.
  5. Write the chemical name of the molecule or ion.

Check your answers by clicking on the molecule. Be sure to rotate the molecule to clearly see its shape from different angles.
