Lua error in package.lua at line 80: module 'strict' not found. Chemical nomenclature, replete as it is with compounds with complex names, is a repository for some very peculiar and sometimes startling names. 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 consequence of simple juxtaposition. Some names derive legitimately from their chemical makeup, from the geographic region where they may be found, the plant or animal species from which they are isolated or the name of the discoverer.

Some are given intentionally unusual trivial names based on their structure, a notable property or at the whim of those who first isolate them. However, many trivial names predate formal naming conventions. Trivial names can also be ambiguous or carry different meanings in different industries, geographic regions and languages.

Godly noted that "Trivial names having the status of INN or ISO are carefully tailor-made for their field of use and are internationally accepted".[1] In his preface to Chemical Nomenclature, Thurlow wrote that "Chemical names do not have to be deadly serious".[2] A website in existence since 1997[3] and maintained at the University of Bristol lists a selection of 'molecules with silly or unusual names' strictly for entertainment. These so-called silly or funny trivial names (of course depending on culture) can also serve an educational purpose. In an article in the Journal of Chemical Education, Dennis Ryan argues that students of organic nomenclature (considered a 'dry and boring' subject) may actually take an interest in it when tasked with the job of converting funny-sounding chemical trivial names to their proper systematic names.[4]

The collection listed below presents a sample of trivial names and gives an idea how chemists are inspired when they coin a brand new name for a chemical compound outside of systematic naming. It also includes some examples of systematic names and acronyms that accidentally resemble English words.

Elements

Glenn Seaborg told his students that he proposed the chemical symbol Pu (from P U) instead of the conventional "Pl" for plutonium as a joke, only to find it officially adopted.[5] Unununium (Uuu) was the former temporary name of the chemical element number 111, a synthetic transuranium element. This element was named roentgenium (Rg) in November 2004.

Compounds

Name based on shape

Barrelene (C8H8), the name derives from the resemblance to a barrel.[6]

The illustration at right shows a generic fenestrane as well as the specific examples [4,4,4,4]fenestrane and [5,5,5,5]fenestrane. Fenestranes are of considerable interest in theoretical chemistry though comparatively few have actually been synthesised.

Named after people

Buckminsterfullerene
Fullerene
Or buckyballs, a form of carbon named after Buckminster Fuller due to its resemblance to Fuller's geodesic domes. The term was coined by Harold Kroto.[9] The alternative name Footballene was coined by A.D.J. Haymet[10] because the molecule also resembles a football.[3]
Bullvalene (tricyclo[3.3.2.02,8]deca-3,6,9-triene) (C10H10), was named by organic chemist Maitland Jones, Jr. for William "Bull" Doering who predicted its properties in 1963.[11][12] Within a specific temperature range the molecule is subject to rapid degenerate Cope rearrangements with the result that all carbon atoms and hydrogen atoms are equivalent and that none of the carbon–carbon bonds is permanent.
Dickite (Al2Si2O5(OH)4), a clay-like material with a number of manufacturing uses, one of which is as a coating for high-quality bond paper. It is named after its discoverer, Dr. W. Thomas Dick.[3]
