- A fullerene is a molecule of carbon in the form of a hollow sphere, ellipsoid, tube, and many other shapes. Spherical fullerenes are also called buckyballs, and they resemble the balls used in football (soccer). Cylindrical ones are called carbon nanotubes or buckytubes.he smallest fullerene is the dodecahedral C 20. There are no fullerenes with 22 vertices. The number of fullerenes C 2n grows with increasing n = 12, 13, 14, ..., roughly in proportion to n 9 (sequence A007894 in OEIS). For instance, there are 1812 non-isomorphic fullerenes C 60.

Benzene The industrial production of benzene relies on three major chemical processes: catalytic reforming, toluene hydrodealkylation, and steam cracking. Another process, called toluene disproportionation, may be used when the goal is to produce aromatics called xylenes (there are three types of xylenes) along with benzene.

Heterocyclic Compounds Examples of this nomenclature are: ethylene oxide = oxacyclopropane, furan = oxacyclopenta-2,4-diene, pyridine = azabenzene, and morpholine = 1-oxa-4-azacyclohexane. The Hantzsch-Widman system provides a more systematic method of naming heterocyclic compounds that is not dependent on prior carbocyclic names.

Cannabis (Marijuana) Dried cannabis buds with visible orange fibers and trychomes. Cannabis, also known as marijuana, weed, pot, grass, dank, ganja, and less commonly, tree, are just some of the most common names for it's use as a psychoactive plant.Species of cannabis include Cannabis sativa, Cannabis indica, and Cannabis ruderalis.hough THC is the main compund resulting in the high associated with marijuana, at least sixty-six other cannabinoids are present in cannabis, including cannabidiol (CBD), cannabinol (CBN), tetrahydrocannabivarin (THCV), among others. These are believed to influence and enhance the effects of THC.

New Form of Carbon is Stronger Than Graphene and Diamond Chemists have calculated that chains of double or triple-bonded carbon atoms, known as carbyne, should be stronger and stiffer than any known material. The sixth element, carbon, has given us an amazing abundance of extraordinary materials. Once there was simply carbon, graphite and diamond. But in recent years chemists have added buckyballs, nanotubes and any number of exotic shapes created out of graphene, the molecular equivalent of chickenwire. So it’s hard to believe that carbon has any more surprises up its sleeve.

- Molecules which do not contain benzene rings are referred to aliphatic (fat-like) compounds. Aromatic molecules with simple alkyl groups as substituents are named as derivatives of benzene. For instance, a benzene with an ethyl group attached to one of the carbons in the ring is simply called ethylbenzene..

Benzene Benzene is an important organic chemical compound with the chemical formula C 6 H 6. Its molecule is composed of 6 carbon atoms joined in a ring, with 1 hydrogen atom attached to each carbon atom.enzene is an aromatic hydrocarbon and the second [ n ]- annulene ([6]-annulene), a cyclic hydrocarbon with a continuous pi bond. It is sometimes abbreviated Ph –H. Benzene is a colorless and highly flammable liquid with a sweet smell.

Carbon: the essentials This is also the thermodynamically most stable form. Diamond is a second form of carbon but is much less common. Other forms of carbon include the fullerenes. Whereas diamond and graphite are infinite lattices, fullerenes such as buckminsterfullerene, C 60, is a discrete molecular species.

- Graphene (/ˈɡræf.iːn/) is an allotrope of carbon in the form of a two-dimensional, atomic-scale, hexagonal lattice in which one atom forms each vertex. It is the basic structural element of other allotropes, including graphite, charcoal, carbon nanotubes and fullerenes.

Noble gas compound Noble gases can also form endohedral fullerene compounds where the noble gas atom is trapped inside a fullerene molecule. In 1993, it was discovered that when C 60 is exposed to a pressure of around 3 bar of He or Ne, the complexes He@C 60 and Ne@C 60 are formed.t was initially believed that the noble gases could not form compounds due to their full valence shell of electrons that rendered them very chemically stable and unreactive. All noble gases have full s and p outer electron shells (except helium, which has no p sublevel), and so do not form chemical compounds easily.

"What is the composition of ""buckyballs?""?" Hettich also analyzed carbon samples known not to contain fullerenes to ensure that none were being created by the laser vaporization process itself. The initial analysis confirmed the presence of both C60 and C70, two common fullerenes, in the shungite sample. To dispel any lingering doubt, Hettich repeated the analysis without a laser, this time using a 400°C stainless steel probe to vaporize the sample and introduce it into the mass spectrometer for ionization.

- The IUPAC name is therefore: 2,5,5-trimethyl-2-hexene. In example (2) the longest chain incorporating both carbon atoms of the double bond has a length of five. There is a seven-carbon chain, but it contains only one of the double bond carbon atoms. Consequently, the root name of this compound will be pentene.

Naming Organic Compounds IUPAC Rules for Cycloalkane Nomenclature 1. For a monosubstituted cycloalkane the ring supplies the root name (table above) and the substituent group is named as usual. A location number is unnecessary. 2. If the alkyl substituent is large and/or complex, the ring may be named as a substituent group on an alkane.3.he following table lists the IUPAC names assigned to simple continuous-chain alkanes from C-1 to C-10. A common ane suffix identifies these compounds as alkanes. Longer chain alkanes are well known, and their names may be found in many reference and text books.
