• Tetrahedral molecular geometryRelated: The ideal tetrahedral angle is approximately 109.5°.

• VSEPR theoryRelated: Predicted repulsions explain why measured bond angles depart from ideal geometries.

• Bond lengthCompared with: It measures molecular direction, whereas bond length measures separation.

• sp² hybridizationRelated: The three ideal sp² directions are separated by angles of 120°.

• Trigonal planar molecular geometryRelated: Angles near 120° are the defining geometric measure of this shape.

• Octahedral molecular geometryRelated: Ideal octahedral positions produce 90° and 180° bond angles.

• Trigonal bipyramidal molecular geometryRelated: The ideal geometry has 120-degree equatorial and 90-degree axial-equatorial angles.

• Square planar molecular geometryRelated: Adjacent square-planar bonds form angles of about 90 degrees; opposite bonds form angles of 180 degrees.
