A Pervasive Molecule Is Captured in a Photograph
But the hydrogen atoms surrounding the benzene ring can be replaced ... than ''valence bonds.'') But 19th-century chemists discovered another molecule containing six carbon atoms that was more difficult to describe in terms of straight-chain architecture ...
Walking Molecules Pick Up Cargo
An organic molecule moves in a straight line and can pick up and transport up to two carbon dioxides from one point ... an organic compound containing a chain of three benzene rings, with two oxygen atoms attached to the central ring, one on each side.
Why Carbon Matters
It forms very stable bonds to itself, first of all. Forming and breaking them (under controlled conditions!) is one of the major challenges of organic synthesis. Carbon atoms can ... you can handle - straight and branched chains, rings, whatever you ...
Organic Chemistry -vs- Inorganic Chemistry
Chemistry ... of hydrogen atoms branching off. Single bonds will abound, but double and even triple bonds will appear. This is because carbon is one of only a few elements that bond to itself to form straight chains, branched chains, rings, and 3 ...
