  2. IUPAC numerical multiplier - Wikipedia

    en.wikipedia.org/wiki/IUPAC_numerical_multiplier

    The numbers 200-900 would be confused easily with 22 to 29 if they were used in chemistry. khīlioi = 1000, diskhīlioi = 2000, triskhīlioi = 3000, etc. 13 to 19 are formed by starting with the Greek word for the number of ones, followed by και (the Greek word for 'and'), followed by δέκα (the Greek word for 'ten').

  3. Bis (benzene)chromium - Wikipedia

    en.wikipedia.org/wiki/Bis(benzene)chromium

    Bis(benzene)chromium is the organometallic compound with the formula Cr(η 6-C 6 H 6) 2. It is sometimes called dibenzenechromium. It is sometimes called dibenzenechromium. The compound played an important role in the development of sandwich compounds in organometallic chemistry and is the prototypical complex containing two arene ligands .

  4. Bisphenol - Wikipedia

    en.wikipedia.org/wiki/Bisphenol

    Bisphenols A (BPA), F (BPF) and S (BPS) have been shown to be endocrine disruptors, potentially relating to adverse health effects. [3] [6] Due to its high production volumes, BPA has been characterised as a "pseudo-persistent" chemical, [7] leading to its spreading and potential accumulation in a variety of environmental matrices, even though it has a fairly short half-life.

    Bisj pole, or Bis pole, is a ritual artifact of the Asmat people of New Guinea; Bismarck Municipal Airport, North Dakota, U.S., IATA code and FAA LID: BIS; See also

  6. Cyclopentadienyl complex - Wikipedia

    en.wikipedia.org/wiki/Cyclopentadienyl_complex

    A famous example of this type of complex is ferrocene (FeCp 2), which has many analogues for other metals, such as chromocene (CrCp 2), cobaltocene (CoCp 2), and nickelocene (NiCp 2). When the Cp rings are mutually parallel the compound is known as a sandwich complex. This area of organometallic chemistry was first developed in

  7. Bisphosphonate - Wikipedia

    en.wikipedia.org/wiki/Bisphosphonate

    3 (phosphonate) groups covalently linked to carbon determine both the name "bisphosphonate" and the function of the drugs. Bis refers to the fact that there are two such groups in the molecule. The long side-chain (R 2 in the diagram) determines the chemical properties, the mode of action and the strength of bisphosphonate drugs.

  8. Cis–trans isomerism - Wikipedia

    en.wikipedia.org/wiki/Cis–trans_isomerism

    Another example of this is the relationship between oleic acid and elaidic acid; oleic acid, the cis isomer, has a melting point of 13.4 °C, making it a liquid at room temperature, while the trans isomer, elaidic acid, has the much higher melting point of 43 °C, due to the straighter trans isomer being able to pack more tightly, and is solid ...

  9. Bicyclic molecule - Wikipedia

    en.wikipedia.org/wiki/Bicyclic_molecule

    In between the prefix and the suffix, a pair of brackets with numerals denotes the number of carbon atoms between each of the bridgehead atoms. These numbers are arranged in descending order and are separated by periods. For example, the carbon frame of norbornane contains a total of 7 atoms, hence the root name heptane. This molecule has two ...
