D2h Ethene

Build ethene, C₂H₄, with the Indigo® 68821W point group molecular model kit to demonstrate D2h point group symmetry, inversion symmetry, and planar geometry. Ideal for undergraduate inorganic chemistry and spectroscopy courses.

The Indigo® 68821W point group molecular model kit builds ethene, C₂H₄, a simple example of the D2h point group. This model identifies all eight D2h symmetry elements. The principal C2 axis, two additional perpendicular C2 axes, the horizontal mirror plane σh, two vertical mirror planes σv, the center of inversion i, and the identity operation E. Other D2h molecules include naphthalene, anthracene, pyrazine, butatriene, and cyclobutadiene, a good cross section of planar aromatic and conjugated examples across structural and spectroscopic chemistry.
