Benzene is a hydrocarbon with the formula C6H6. This prototypical aromatic compound is a sweet smelling liquid that boils at 80 °C and freezes at 5.5 °C. Its hexagonal symbol has become a ubiquitous mascot of chemistry itself. Benzene was discovered in 1825 by Michael Faraday when he distilled gum benzoin, a plant resin rich in benzoic acid. In 1855, August Wilhelm von Hofmann realized that many odorous compounds had chemical reactivity similar to benzene, and he coined the term

Benzene is a hydrocarbon with the formula C6H6. This prototypical aromatic compound is a sweet smelling liquid that boils at 80 °C and freezes at 5.5 °C. Its hexagonal symbol has become a ubiquitous mascot of chemistry itself. Benzene was discovered in 1825 by Michael Faraday when he distilled gum benzoin, a plant resin rich in benzoic acid. In 1855, August Wilhelm von Hofmann realized that many odorous compounds had chemical reactivity similar to benzene, and he coined the term "aromatic". Due to the limited theory of bonding at the time, chemists struggled with the true structure of C6H6. Experiments showed that it was totally symmetric, but all the proposed symmetric structures had humorously impossible amounts of ring strain. In 1865, August Kekulé proposed the structure of alternating single and double bonds, with total symmetry arising from "rapid oscillation" between the bond types. This early form of resonance theory finally gained wide acceptance in 1890. Later quantum mechanics showed that benzene's symmetry and stability are due to donut-shaped regions of delocalized electrons both above and below the plane. Industrially, benzene is a major petrochemical obtained from catalytic reforming, which turns naphtha into BTX (benzene, toluene, and xylenes). BTX is added to gasoline, but is nowadays skewed to minimal benzene content for toxicity reasons. Therefore, the polymer industries that require massive amounts of benzene as precursor may instead obtain it by toluene hydrodealkylation, toluene disproportionation, or naphtha steam reforming. Application-wise, 50% of benzene is converted to ethylbenzene (for polystyrene), 20% to cumene (for phenolic resins), and 10% to cyclohexane (for nylon). Chronic exposure to benzene from gasoline or other sources is a worldwide health problem since it causes DNA damage and cancer, especially leukemia. As early as 1848, it was recognized by the American Petroleum Institute that "the only absolutely safe concentration for benzene is zero". #forbiddensnacks #chemistry #organicchemistry #inorganicchemistry #chemistrylab #chemistry_lab #chemistrylife #chemistrylifestyle #chemistryfun #chemistryisfun #chemistrylove #benzene ...

Houseplants can filter out harmful toxins and help clean the air! Here’s some great house plants. I have 2 of these 8 😑😑! I have a #bamboo plant but it’s not a #bamboopalm 🍃💚 ✨

On Saturday, protestors scaled the 275ft smokestacks at the Cricket Valley Fracked Gas Energy Facility. Watch as Dutchess County farmer, Ben, shows us how close CVE is to schools and NY’s unique Great Swamp.

There is much at stake, across state lines. CVE will be processing fracked gas brought in from Pennsylvania and emitting harmful chemicals throughout NY and surrounding states.

We demand that the environmental impact of this facility be re-evaluated.
