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.
The main structure of chemical names according to IUPAC nomenclature. IUPAC nomenclature is a set of recommendations for naming chemical compounds and for describing chemistry and biochemistry in general. The International Union of Pure and Applied Chemistry (IUPAC) is the international authority on chemical nomenclature and terminology.
The names "caffeine" and "3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione" both signify the same chemical compound. The systematic name encodes the structure and composition of the caffeine molecule in some detail, and provides an unambiguous reference to this compound, whereas the name "caffeine" simply names it.
For groups of compounds named after a simple parent compound, articles about the group should be located at the plural of the parent compound name, e.g. hydrazines, silanes, boranes, diphosphenes. Similarly, salts and esters of carboxylic acids should collectively be referred to by the plural of the carboxylate.
In chemistry, a number of prefixes, suffixes and infixes are used to describe the type and position of the functional groups in the compound. The steps for naming an organic compound are: [5] Identification of the most senior group. If more than one functional group, if any, is present, the one with highest group precedence should be used.
Classic Chemistry. Based on Guyton de Morveau, Louis Bernard; Lavoisier, Antoine; Bertholet, Claude-Louis; Fourcroy, Antoine-François de (1788) [1787]. Method of chymical nomenclature, proposed by Messrs. de Morveau, Lavoisier, Bertholet, and de Fourcroy: To which is added A new system of chymical characters adapted to the nomenclature by Mess.
Longer chains were to have their names derived from the appropriate Greek numeral e.g. pent (pentane), hex (hexane) etc. When naming compounds with side chains the name would be determined by the longest straight chain with a substituted group e.g. methyl propane (CH 3 CH(CH 3 )CH 3 )
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
