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 ...
The YouTube channel is now one of the most popular chemistry related channels on all of YouTube. [7] The producers of the videos have received praise from Nobel Laureates, chemistry professors, and the general public, says Professor Poliakoff. [5] Chemistry Nobel Laureate Roald Hoffmann has even offered his praise of the videos, stating they ...
For example, in the CAS scheme "group VIIB" denotes manganese group (group 7), while in the old IUPAC scheme it denotes halogen group (group 17). If they are used at all, context should clarify (disambiguate) into the 1–18 numbering. Care should be taken when translating old sources that use this nomenclature to modern terminology.
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.
Multiplicative nomenclature is to be preferred over simple substitutive if it can be used. This is the nomenclature with an apostrophe after numbers such as 4'; it allows multiple occurrences of the principal characteristic group or compound class to be treated together. Example: 4,4′-sulfanediyldibenzoic acid refers to (COOH-C 6 H 4) 2 S.
Nomenclature (UK: / n oʊ ˈ m ɛ ŋ k l ə tʃ ə, n ə-/, US: / ˈ n oʊ m ə n k l eɪ tʃ ər /) [1] [2] is a system of names or terms, or the rules for forming these terms in a particular field of arts or sciences. [3] (The theoretical field studying nomenclature is sometimes referred to as onymology or taxonymy [4]).
The IUPAC Nomenclature for Organic Chemical Transformations is a methodology for naming a chemical reaction.. Traditionally, most chemical reactions, especially in organic chemistry, are named after their inventors, the so-called name reactions, such as Knoevenagel condensation, Wittig reaction, Claisen–Schmidt condensation, Schotten–Baumann reaction, and Diels–Alder reaction.
