Td CH4 Methane

Build methane, CH₄, with the Indigo® 68821W point group molecular model kit to demonstrate Td point group symmetry and tetrahedral geometry. Ideal for undergraduate inorganic chemistry and spectroscopy courses covering cubic point groups.

The Indigo® 68821W point group molecular model kit builds methane, CH₄, the most widely taught example of the Td point group with perfect tetrahedral geometry. Students can identify the full set of Td symmetry elements, the four C3 axes, three C2 axes, three S4 improper rotation axes, and six σd dihedral mirror planes. This kit can build other Td molecules such as carbon tetrachloride, (CCl₄), and adamantane, for comparison of a simple tetrahedron to a more complex cage structure that shares the same underlying symmetry.
