Chemical nomenclature however (with IUPAC nomenclature as the best example) is necessarily more restrictive: Its purpose is to standardize communication and practice so that, when a chemical term is used it has a fixed meaning relating to chemical structure, thereby giving insights into chemical properties and derived molecular functions. These ...
Chemical formulae with deuterated solvents (for example, in NMR use) are customarily described with "D" as chemical symbol: CD 3 OD, methanol-d 4; CD 3 SOCD 3, DMSO-d 6 (regular notation would be C 2 H 3 O 2 H). These established systems are acceptable, provided they are consistent within an article.
The Geneva Nomenclature of 1892 was created as a result of many other meetings in the past, the first of which was established in 1860 by August Kekulé. Another entity called the International Association of Chemical Societies (IACS) existed, and on 1911, gave vital propositions the new one should address: [ 2 ]
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.

The IUPAC nomenclature is a system of naming chemical compounds and for describing the science of chemistry in general. It is maintained by the International Union of Pure and Applied Chemistry . the Blue Book [ 45 ] [ 46 ] and the Red Book : [ 47 ] the two publications containing the rules for naming organic and inorganic compounds .
The subunits that make up each of these structures are identified, i.e., the largest divalent groups that can be named using IUPAC nomenclature of organic chemistry. In the example, the two-carbon ethylidene unit is longer than two separate one-carbon methanediyl units. Figure 1. The order of subunit precedence.
In chemical nomenclature, a preferred IUPAC name (PIN) is a unique name, assigned to a chemical substance and preferred among all possible names generated by IUPAC nomenclature. The "preferred IUPAC nomenclature" provides a set of rules for choosing between multiple possibilities in situations where it is important to decide on a unique name.
