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 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.
additive naming ([MnFO 3] fluoridotrioxidomanganese) Additionally there are recommendations for the following: naming of cluster compounds; allowed names for inorganic acids and derivatives; naming of solid phases e.g. non-stoichiometric phases; For a simple compound such as AlCl 3 the different naming conventions yield the following:
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.
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.
