Chemical nomenclature, replete as it is with compounds with very complex names, is a repository for some names that may be considered unusual. A browse through the Physical Constants of Organic Compounds in the CRC Handbook of Chemistry and Physics (a fundamental resource) will reveal not just the whimsical work of chemists, but the sometimes peculiar compound names that occur as the ...
Here is a sample molecule with the parent carbons numbered: For simplicity, here is an image of the same molecule, where the hydrogens in the parent chain are removed and the carbons are shown by their numbers: Now, following the above steps: The parent hydrocarbon chain has 23 carbons. It is called tricosa-.
The main purpose of chemical nomenclature is to disambiguate the spoken or written names of chemical compounds: each name should refer to one compound. Secondarily, each compound should have only one name, although in some cases some alternative names are accepted. Preferably, the name should also represent the structure or chemistry of a compound.
PG5 has a molecular mass of about 200 MDa or 200,000,000 g/mol. It has roughly 20 million atoms and a diameter of roughly 10 nm. Its length is up to a few micrometers. [3]
The substituents are any functional groups attached to the main carbon chain. The main carbon chain is the longest possible continuous chain. The chemical affix denotes what type of molecule it is. For example, the ending ane denotes a single bonded carbon chain, as in "hexane" (C 6 H 14). [30] Another example of IUPAC organic nomenclature is ...
This molecule has several very interesting properties; one is its very high basicity; another is its spectroscopic properties. With a pK a of 12.34 [4] for its conjugate acid in aqueous solution, 1,8-bis(dimethylamino)naphthalene is one of the strongest organic bases. However, it only absorbs protons slowly—hence the trade
The first reaction with many volatile organic compounds (VOCs) is the removal of a hydrogen atom, forming water and an alkyl radical (R •): • HO + RH → H 2 O + R • The alkyl radical will typically react rapidly with oxygen forming a peroxy radical: R • + O 2 → RO 2
The number 1 can be omitted when there is only one isomeric state, e.g. tantalum-180m, 180m Ta. You may use a nuclide template. Corresponding letters also used in literature, these are not used in this wiki: m n p q . The hydrogen isotopes are exceptions where the common special names may be used: Protium (= hydrogen-1, 1 H).
