Explore linear molecular geometry with the Indigo® VSEPR model kit. Visualize 180° bond angles and learn how electron pairs shape molecular structure.

The Indigo® Molecular Geometry VSEPR Kit includes a model that demonstrates linear molecular geometry, where two electron domains around a central atom orient 180° apart. This shape is characteristic of molecules such as BeCl2 and CO2 , where repulsion between bonding pairs minimizes overlap, resulting in a straight-line configuration.

Learning Outcomes

Learning Outcome Activity Concept Reinforced Curricular Link
Identify linear geometry from electron domain arrangement. Assemble central atom with two bonded pairs and no lone pairs. Electron pair repulsion minimizes overlap at 180°. High school chemistry: molecular geometry basics.
Relate geometry to hybridization and bonding. Compare sp hybrid orbitals with trigonal and tetrahedral models. Geometry arises from hybridization type (sp = linear). Introductory college chemistry: orbital theory.
Predict polarity based on symmetry. Contrast CO2 (nonpolar) vs. SO2 (bent) using the model. Symmetry determines cancellation of dipoles. Physical chemistry & bonding concepts.
