Hydrocarbon Structure and Chemistry: Aromatics
Hydrocarbons are organic compounds consisting of C-C and C-H bonds. Carbon has a valence of four and thus requires four electrons or bonds to complete its octet in the neutral state. Hydrogen has a valence of one and thus requires a single electron or bond to complete its "duet" in the neutral state. Thus in hydrocarbons carbon can form neutral bonding arrangements by forming single bonds with ...
متن کاملNew Adsorbents for Purification: Selective Removal of Aromatics
Adsorption of benzene and cyclohexane on ®arious Y-zeolites was in®estigated to de®elop sorbents for the purification of aliphatics by remo®al of aromatics. Ag-Y showed superior benzenercyclohexane selecti®ities to Na-Y, Pd-Y, and H-USY. Separation factors greater than 10 5 were obtained with Ag-Y at low concentrations of benzene. High selecti®ities were achie®ed by the strong interaction betwe...
متن کاملUltrathin oxide films on metals: new physics and new chemistry?
Oxide thin films on metals are now currently used as model systems to study the surface properties of highly insulating oxides by means of electron spectroscopies. However, it has been recently proposed that ultrathin oxide films and oxide–metal interfaces may actually have unprecedented intrinsic chemical–physical properties, because of image potential screening of charge fluctuations and inte...

متن کاملContorted polycyclic aromatics.
CONSPECTUS: This Account describes a body of research in the design, synthesis, and assembly of molecular materials made from strained polycyclic aromatic molecules. The strain in the molecular subunits severely distorts the aromatic molecules away from planarity. We coined the term "contorted aromatics" to describe this class of molecules. Using these molecules, we demonstrate that the curved ...
