Ethane symmetry number
WebJan 25, 2024 · Ethane is a colourless, odourless, and flammable gas having two carbon (C) atoms and six hydrogens (H) atoms. It’s only composed of carbon and hydrogen atoms, so it is classified as a hydrocarbon. The … The symmetry number or symmetry order of an object is the number of different but indistinguishable (or equivalent) arrangements (or views) of the object, that is, it is the order of its symmetry group. The object can be a molecule, crystal lattice, lattice, tiling, or in general any kind of mathematical object that admits symmetries.
