S4NGA = 50 × M11A2 Practice HEAT Rifle Grenades packed in fiberboard storage tubes in a wooden crate with 5 metal M13 Grenade Launcher Assortment ammo cans (1 carton of 10 × .30-'06 Grenade Blank M3 cartridges, 1 carton of 6 × .30 Carbine Grenade Blank M6 cartridges, and 1 packet of 5 × M7 Grenade Auxiliary Cartridges).
For example, the three isomers of xylene CH 3 C 6 H 4 CH 3, commonly the ortho-, meta-, and para-forms, are 1,2-dimethylbenzene, 1,3-dimethylbenzene, and 1,4-dimethylbenzene. The cyclic structures can also be treated as functional groups themselves, in which case they take the prefix "cyclo alkyl -" (e.g. "cyclohexyl-") or for benzene, "phenyl-".

IUPAC states that, "As one of its major activities, IUPAC develops Recommendations to establish unambiguous, uniform, and consistent nomenclature and terminology for specific scientific fields, usually presented as: glossaries of terms for specific chemical disciplines; definitions of terms relating to a group of properties; nomenclature of chemical compounds and their classes; terminology ...
Ordnance crest "WHAT'S IN A NAME" - military education about SNL. This is a historic (index) list of United States Army weapons and materiel, by their Standard Nomenclature List (SNL) group and individual designations — an alpha-numeric nomenclature system used in the United States Army Ordnance Corps Supply Catalogues used from about 1930 to about 1958.
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.
In the example, there is a bromo-substituted -CH 2-CH 2 - subunit. 1-Bromoethane-1,2-diyl is chosen in preference to 2- bromoethane-1,2-diyl as the former has a lower locant for the bromo-substituent. The preferred CRU is therefore oxy(1-bromoethane-1,2-diyl) and the polymer is thus named poly[oxy(1-bromoethane-1,2-diyl)].
decacarbonyl-1κ 3 C,2κ 3 C,3κ 4 C-di-μ-hydrido-1:2κ 2 H;1:2κ 2 H-triangulo-(3 Os—Os), (Decacarbonyldihydridotriosmium). decacarbonyl-1κ 3 C,2κ 3 C,3κ 4 C shows that there are three carbonyl groups on two osmium atoms and four on the third. di-μ-hydrido-1:2κ 2 H;1:2κ 2 H specifies that the two hydride bridge between the osmium atom ...
