Carbon structural arrangement

The basic building block of carbon is a planar sheet of carbon atoms arranged in a honeycomb structure (called graphene or basal plane). These carbon sheets are stacked in an ordered or disordered manner to form crystallites. Each crystallite has two different edge sites (Fig. 2) the armchair and zig-zag sites. In graphite and other ordered carbons, these edge sites are actually the crystallite planes, while in disordered soft and hard carbons these sites, as a result of turbostratic disorder, may not... 

D-myo-inositol is a six carbon polyalcohol in a ring structure arranged in a chair configuration. 

The structural arrangement of group 11 amidinate complexes is determined by the substituents on the amidinate aryl groups as well as on the NCN carbon [14,19]. The electronic vs. steric effect of the substituents on the molecular arrangement of gold(I) amidinate complexes have been studied in detail in the Fackler laboratory. 

Fullerenes (originally buckminsterfullerenes) are a new class of carbon-only molecules the first example discovered in 1985 (Kroto et al., 1985), being composed of 60 carbon atoms arranged in a soccer ball structure (C60). The condensed aromatic... 

The first strnctnre has the carbon atoms arranged in a linear fashion and is called normal butane or, simply, n-bntane. The second has a branched structure and is termed tTobntane (or, more rigoronsly, 2-methylpropane). 

It is well known that the boiling points of normal paraffins increase with the number of carbon atoms. What patterns can we observe about how the structure arrangements affect the boiling points of paraffins. Here are the data of the boiling points for paraffins with one to seven carbon atoms ... 

PGC sorbents have even more highly homogeneous hydrophobic surfaces than GCB sorbents. PGCs are macroporous materials composed of flat, two-dimensional layers of carbon atoms arranged in graphitic structure. The flat, homogeneous surface of PGC arranged in layers of carbons with delocalized n electrons makes it uniquely capable of selective fractionation between planar and nonplanar analytes such as the polychlorinated biphenyls [92,94,95],... 

From the electronic structure of the lead atom, one would expect the tetraorganolead compounds to form via an spz hybridization of the two s and two p electrons in the outer shell of the lead atom, with the carbon atoms arranged in a tetrahedral configuration around the lead atom. All...
