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 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 ...
متن کاملAntioxidant Capacity of Berry Crops, Culinary Herbs and Medicinal Herbs
Herbs and berry crops have been shown to contain high levels of antioxidant compounds. These antioxidants are capable of performing a number of functions including acting as free radical scavengers, peroxide decomposers, singlet and triplet oxygen quenchers, enzyme inhibitors, and synergists. The different antioxidant components found in herbs and berry crops provide protection against harmful ...
