  2. IUPAC numerical multiplier - Wikipedia

    en.wikipedia.org/wiki/IUPAC_numerical_multiplier

    The numbers 200-900 would be confused easily with 22 to 29 if they were used in chemistry. khīlioi = 1000, diskhīlioi = 2000, triskhīlioi = 3000, etc. 13 to 19 are formed by starting with the Greek word for the number of ones, followed by και (the Greek word for 'and'), followed by δέκα (the Greek word for 'ten').

  3. Numeral prefix - Wikipedia

    en.wikipedia.org/wiki/Numeral_prefix

    The root language of a numerical prefix need not be related to the root language of the word that it prefixes. Some words comprising numerical prefixes are hybrid words. In certain classes of systematic names, there are a few other exceptions to the rule of using Greek-derived numerical prefixes.

  4. IUPAC nomenclature of organic chemistry - Wikipedia

    en.wikipedia.org/wiki/IUPAC_nomenclature_of...

    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.

  5. List of chemistry mnemonics - Wikipedia

    en.wikipedia.org/wiki/List_of_chemistry_mnemonics

    The prefixes for naming carbon chains containing one to four carbons. For chains containing five or more carbons, the inorganic prefixes (e.g. pent = 5, hept = 7) are used. M eth

  6. Greek letters used in mathematics, science, and engineering

    en.wikipedia.org/wiki/Greek_letters_used_in...

    Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities. In these contexts, the capital letters and the small letters represent distinct and unrelated entities.

  8. Alk- - Wikipedia

    en.wikipedia.org/wiki/Alk-

    Prefixes, suffixes, and infixes are known as organic chemistry affixes. These affixes provide details about the molecule's structure, such as the quantity of carbon atoms, the kind of carbon-to-carbon bonds, and the existence of functional groups. [2] The following are a few typical additions in organic chemistry: Prefixes

  9. Metric prefix - Wikipedia

    en.wikipedia.org/wiki/Metric_prefix

    The first uses of prefixes in SI date back to the definition of kilogram after the French Revolution at the end of the 18th century. Several more prefixes came into use, and were recognised by the 1947 IUPAC 14th International Conference of Chemistry [5] before being officially adopted for the first time in 1960. [6]
