	IUPAC nomenclature (Site not responding. Last check: 2007-10-22)
		IUPAC nomenclature is a systematic way of naming organic chemical compounds as recommended by the International Union of Pure and Applied Chemistry (IUPAC).
		In IUPAC nomenclature, a number of prefixes, suffixes and infixes are used to describe the type and position of functional groups in the compound.
		The IUPAC nomenclature scheme becomes rapidly more elaborate for more complex cyclic structures, with notation for compounds containing conjoined rings, and many common names such as phenol, furan, indole, etc. being accepted as base names for compounds derived from them.

		It is not difficult to argue that IUPAC has neglected, if not turned its back on, one of its potentially most important constituencies: the international community of chemists affiliated with the union.
		IUPAC needs the widest possible support and engagement of the global community of chemists to achieve its aims, in the same way that chemists need the support of their international union to develop and maintain the standards, values, and ethics of chemistry and to promote the public's appreciation of the science.

	Element 106 name change being reconsidered (Site not responding. Last check: 2007-10-22)
		Last fall, the IUPAC nomenclature committee stunned the scientific community by rejecting the names proposed for elements 104 to 108 by their discoverers and submitting their own names instead (see Currents, Oct. 14, 1994).
		According to the CandEN report, the IUPAC executive committee has bowed to the pressure and is now recommending that the IUPAC names be reverted back to a "provisional" status.
		If the names of 106 and the other transuranium elements in question are submitted for public debate, chemists will have five months to submit their comments through one of 19 centers around the world.

		In certain areas, and particularly in metrology, it is important for IUPAC to retain consistency with definitions given by ‘higher authorities’ such as in the International Vocabulary of Basic and General Terms in Metrology [VIM; ref.
		For the same reason, general laboratory slang, pertaining to a particular field, should not be used in written reports, as this will often not be understood by readers versed in related areas of chemistry, who nevertheless wish to gain an understanding of the new field.

	Articles: Elementary, my dear IUPAC
		That’s because the rules, laid down by IUPAC (the International Union of Pure and Applied Chemistry, based in Oxford) say that no chemical element may be named for a living person.
		The last proposal from IUPAC was presented to its annual conference in 1994 but could not be agreed; a new round of consultation based on a revised list of names finished at the end of May 1996 and it is hoped to announce the results at the 1997 General Assembly.
		The strangest part of this whole dispute is that in some cases only a single atom of the element has ever been identified, and that all the atoms have in any case long since decayed—the longest half life of any of them is 70 seconds.

		To address the problem, IUPAC should encourage and facilitate the coordination of the variety of initiatives proposed, with a view to enhancing the importance of chemical education at all levels, and to utilize younger chemists to promote the subject and its achievements.
		It is recommended that IUPAC collaborate with industry, trade associations, learned societies and academe to discuss how best to achieve these aims.
		The discussion of the proposal made it clear that Council was not approving an unlimited expenditure, but rather that the amount to be spent on this effort would be determined by the Executive Committee.

	IUPAC Names
		This other method is called the IUPAC method (from the International Union of Pure and Applied Chemistry) and it involves picking out the longest continuous chain of carbon atoms, then identifying what groups are attached to that chain and indicating where they are attached.
		This compound has four carbon atoms lined up one after the other, so its IUPAC name is butane.
		The IUPAC name for the other structural formula is methylpropane (or 2-methylpropane).

		The IUPAC system requires first that we have names for simple unbranched chains, as noted above, and second that we have names for simple alkyl groups that may be attached to the chains.
		Double bonds precede triple bonds in the IUPAC name, but the chain is numbered from the end nearest a multiple bond, regardless of its nature.

	Periodic table group
		There is considerable confusion surrounding the two old systems in use (old IUPAC and CAS) that combined the use of Roman numerals with letters.
		In the old IUPAC system the letters A and B were designated to the left (A) and right (b) part of the table, while in the CAS system the letters A and B were designated to main group elements (A) and transition elements (B).
		The new IUPAC scheme was developed to replace both systems as they confusingly used the same names to mean different things.
