What is dodecahedrane used for?
What is dodecahedrane used for?
Dodecahedrane does not occur in nature and has no significant uses. It was synthesized by Leo Paquette in 1982, primarily for the “aesthetically pleasing symmetry of the dodecahedral framework”.
What is C20 in chemistry?
Dicarbon monoxide (C2O) is a molecule that contains two carbon atoms and one oxygen atom. It is a linear molecule that, because of its simplicity, is of interest in a variety of areas. It is, however, so extremely reactive that it is not encountered in everyday life.
What molecules have 20 atoms?
One molecule of vitamin C is made up of 20 atoms (6 carbons, 8 hydrogens, and 6 oxygens – that’s C6H8O6).
What is the name of h25?
| Chemical Component Summary | |
|---|---|
| Name | 5-Chloro-thiophene-2-carboxylic acid ((3S,4S)-1-{[2-fluoro-4-(2-oxo-2H-pyridin-1-yl)-phenylcarbamoyl]-methyl}-4-hydroxy-pyrrolidin-3-yl)-amide |
| Identifiers | 5-chloro-N-[(1S,3S,4S)-1-[2-[[2-fluoro-4-(2-oxopyridin-1-yl)phenyl]amino]-2-oxo-ethyl]-4-hydroxy-pyrrolidin-3-yl]thiophene-2-carboxamide |
How many rings are in cubane?
For cubane, we thus have 12−8+1=5 rings.
Is cubane reactive?
A solid crystalline substance, cubane is one of the Platonic hydrocarbons. Therefore, cubane compounds are highly reactive, which in principle may make them useful as high-density, high-energyfuels and explosives (for example, octanitrocubane and heptanitrocubane).
Is carbon a atom?
6
Carbon/Atomic number
Carbon atoms comprise a nucleus of neutrons and six protons surrounded by six electrons. Quantum mechanics dictates that the first two electrons occupy the inner atomic orbital, while the remaining four electrons have wavefunctions that only half-fill the second standard and three second principal orbitals.
What are the derivatives of dodecahedrane?
A variety of dodecahedrane derivatives have been synthesized and reported in the literature. Substitution of all 20 hydrogens by fluorine atoms yields the relatively unstable perfluorododecahedrane C 20 F 20, which was obtained in milligram quantities.
What is an annnelated dodecahedrane?
Annelated dodecahedrane structures have been proposed. Molecules whose framework forms a closed cage, like dodecahedrane and buckminsterfullerene, can encapsulate atoms and small molecules in the hollow space within. Those insertions are not chemically bonded to the caging compound, but merely mechanically trapped in it.
What are the characteristics of a regular dodecahedron?
While the regular dodecahedron shares many features with other Platonic solids, one unique property of it is that one can start at a corner of the surface and draw an infinite number of straight lines across the figure that return to the original point without crossing over any other corner.
How many stellations does a dodecahedron have?
Great stellated dodecahedron. The convex regular dodecahedron also has three stellations, all of which are regular star dodecahedra. They form three of the four Kepler–Poinsot polyhedra. They are the small stellated dodecahedron {5/2, 5}, the great dodecahedron {5, 5/2}, and the great stellated dodecahedron {5/2, 3}.
