Molecules with Silly or Unusual Names

inoshitalite

Although it sounds like the trade name of a laxative, this is a type of mica found in Japan and Sweden, and has the formula (Ba,K)(Mg,Mn)₃Si₂Al₂O₁₀(OH)₂. It is green and vitreous, and is about as hard as fingernails, apparently. Its name comes from the Japanese for "under the tree" (ki = tree; no = possessive particle; shita = under).

Bastadin-5

This is just one of a number of bastadins, which are molecules isolated from the marine sponge Ianthella basta. They possess antibacterial, cytotoxic and anti-inflammatory properties.

Fucitol

Although this sounds like what an undergraduate chemist might exclaim when their synthesis goes wrong, it's actually an alcohol, whose other names are L-fuc-ol or 1-deoxy-D-galactitol. It gets its wonderful trivial name from the fact that it is derived from the sugar fucose, which comes from a seaweed found in the North Atlantic called Bladderwrack whose latin name is Fucus vesiculosis. Interestingly, there are a few articles in the Journal of Biochemistry throughout 1997 concerning a kinase enzyme which acts on fucose. The creators of these articles were Japanese, and seemed to have missed the fact that fucose kinase should not be abbreviated as 'fuc-K'. Similarly, the E. coli K-12 Gene has other proteins that have been named Fuc-U and Fuc-R.

Erotic Acid

No, this isn't the world's best aphrodisiac. Its correct name is orotic acid, but it has been misspelt so often in the chemical literature that it is also known as erotic acid! Another name for it is vitamin B13. Apparently, if you add another carbon to it, it becomes homo-erotic acid...

Fukalite

This wonderfully named mineral gets its name from the Fuka mine in the Fuka region of southern Japan. It is very rare, and is a form of calcium silico-carbonate, with formula Ca₄Si₂O₆(CO₃)(OH,F)₂.

Traumatic Acid

This is a plant hormone which causes injured cells to divide and help repair the trauma - hence its name, and its synonym 'wound hormone'.

Arabitol

No, this has nothing to do with rabbits - it's an organic alcohol that's one constituent of wine. It's also known as pentahydric alcohol. A related sugar molecule, arabinose, also has nothing to do with rabbits, nor with the size of a Rabbi's nose (A Rabbi Nose).

Curious Chloride and Titanic Chloride

The trivial name for some curium compounds can be either curous or 'curious', so curium trichloride becomes curious chloride. However the only curious property it has is that it's sufficiently radioactive that a solution, if concentrated enough, will boil spontaneously after a while. (I wonder if a molecule with 2 Cm atoms in would be 'bi-curious'...?)
In a similar way, titanium compounds can be 'titanic', so we get the wonderfully named titanic chloride, TiCl₄. It's also interesting to know that in the titanium industry, TiCl₄ is known as 'tickle'. Furthermore, curium oxides are called 'curates', so the titanium compound would be Titanic Curate, and since curium can have more than one valency we could end up with Curious Curates. But I'm sure these are already a well-known phenomenon...
In a similar way, some nickel compounds can be referred to as 'nickelous' - so we get compounds like Nickelous Sulfate (a nice guy by all accounts...)

Putrescine, Cadaverine, Spermine and Spermidine

Putrescine originates in putrefying and rotting flesh, and is quite literally, the smell of death. It is one of the breakdown products of some of the amino-acids found in animals, including humans. Although the molecule is a poisonous solid, as flesh decays the vapour pressure of the putrescine it contains becomes sufficiently large to allow its disgusting odour to be detected. It is usually accompanied by cadaverine (named after the cadavers that give rise to it), a poisonous syrupy liquid with an equally disgusting smell. Putrescine and cadaverine also contribute towards the smells of some living processes. Since they are both poisonous, the body normally excretes them in whatever way is quickest and most convenient. For example, the odour of bad breath and urine are 'enriched' by the presence of these molecules, as is the 'fishy' smell of the discharge from the female medical condition bacterial vaginosis. Putrescine and cadaverine also contribute to the distinctive smell of semen, which also contains the related molecules spermine and spermidine.

Unununium

I know this is technically an element, not a molecule, but it had such a ridiculous name I thought I'd include it. This is actually element number 111, and was called by the IUPAC temporary systematic name of unununium before it was recently renamed roentgenium. This is a pity, because if it formed ring or cage structures, previously we might have ended up with unununium onions...

Cummingtonite

This mineral must have the silliest name of them all! Its official name is magnesium iron silicate hydroxide, and it has the formula (Mg,Fe)₇Si₈O₂₂(OH)₂. It got its name from the locality where it was first found, Cummington, Massachusetts, USA.

Megaphone

Despite having a ridiculous name, the molecule is quite ordinary. It gets its name from being both a constituent of Aniba Megaphylla roots and a ketone.

Munchnones

No, these aren't the favourite compound of the Munchkins from The Wizard of Oz, but are in fact a type of mesoionic compound. These are ring structures in which the positive and negative charge are delocalised, and which cannot be represented satisfactorily by any one polar structure. They got their name when Huisgen called them after the city Munich (München), after similar compounds were called sydnones after Sydney.

Buckminster Fullerene

This is the famous soccerball-shaped molecule that won its discoverers the Nobel prize for Chemistry in 1996. It is named after the architect Buckminster Fuller who designed the geodesic dome exhibited at Expo '67 in Montreal, from which Sir Harry Kroto got the idea how 60 Carbon atoms could be arranged in a perfectly symmetrical fashion. Because the name of the molecule is a bit of a mouthful, it is often referred to just as a Bucky Ball. It's also known as 'Footballene' by some researchers. In fact, there is now a whole 'fullerene zoo', with oddly coined names, including: Buckybabies (C₃₂, C₄₄, C₅₀, C₅₈), Rugby Ball (C₇₀), Giant Fullerenes (C₂₄₀, C₅₄₀, C₉₆₀), Russian Egg or Bucky Onions (balls within balls), Fuzzyball (C₆₀H₆₀), Bunnyball (C₆₀(OsO₄)(4-t-Butylpyridine)₂), Platinum-Burr Ball ({[(C₂H₅)₃P]₂Pt}₆C₆₀) and Hetero-fullerenes (in which some Cs are replaced by other atoms).
There is also a fullerene paper in which the authors describe a method for severing two adjacent bonds in C₆₀, entitled "There Is a Hole in My Bucky" [J. Am. Chem. Soc., 117 (1995) 7003].

Bastardane

This is actually a close relative of adamantane, and its proper name is ethano-bridged noradamantane. However because it had the unusual ethano bridge, and was therefore a variation from the standard types of structure found in the field of hydrocarbon cage rearrangements, it came to be known as bastardane - the "unwanted child".

Adamantane

This molecule always brings a smile to the lips of undergrads when they first hear its name, especially in the UK. For those not in the know, Adam Ant was an English pop star in the early 1980's famous for silly songs and strange make-up.

Arsole

Yes, believe it or not, there is actually a molecule called Arsole... and it's a ring! It is the arsenic equivalent of pyrrole, and although it is rarely found in its pure form, it is occasionally seen as a sidegroup in the form of organic arsolyls. For more information, see the paper with probably the best title of any scientific paper I've ever come across: "Studies on the Chemistry of the Arsoles", G. Markl and H. Hauptmann, J. Organomet. Chem., 248 (1983) 269. Contrary to popular belief, new research (see reference below) shows that arsoles are only moderately aromatic... Incidentally US patent number US 3 412 119 by the Dow Chemical Company is entitled 'Substituted Stannoles, Phospholes, Arsoles, and Stiboles' - I didn't know there was a substitute for an arsole...
Furthermore, the structure where arsole is fused to a benzene ring is called 'benzarsole', and apparently when it's fused to 6 benzenes it would be called 'sexibenzarsole' (although that molecule hasn't been synthesised yet). Another well known poisonous arsenic molecule is the simple hydride, called 'arsine', with formula AsH₃.
And on a related theme, I've been told of an Aryl Selenide compound with the superb shorthand of ArSe, which is both toxic and smelly. The paper it comes from in J. Am. Chem. Soc. was published by authors from, of course, the University of Aarhus!
Also, the related molecule phosphole (which just replaces As with P) is quite amusing if you are a French speaker, since it's pronounced the same as 'fausse folle' (literally false woman), which means both a 'crazy woman' and a 'drag-queen' or 'ladyboy'.

Chemistry

2008-01-21T20:40:00.000-08:00

Chemistry (from Egyptian kēme (chem), meaning "earth"^[1]) is the science concerned with the composition, structure, and properties of matter, as well as the changes it undergoes during chemical reactions.^[2] Historically, modern chemistry evolved out of alchemy following the chemical revolution (1773). Chemistry is a physical science related to studies of various atoms, molecules, crystals and other aggregates of matter whether in isolation or combination, which incorporates the concepts of energy and entropy in relation to the spontaneity of chemical processes.

Disciplines within chemistry are traditionally grouped by the type of matter being studied or the kind of study. These include inorganic chemistry, the study of inorganic matter; organic chemistry, the study of organic matter; biochemistry, the study of substances found in biological organisms; physical chemistry, the energy related studies of chemical systems at macro, molecular and submolecular scales; analytical chemistry, the analysis of material samples to gain an understanding of their chemical composition and structure. Many more specialized disciplines have emerged in recent years, e.g. neurochemistry the chemical study of the mind (see subdisciplines).
