The prefix form is "carbamoyl-". e.g., HCONH 2 methanamide, CH 3 CONH 2 ethanamide. Amides that have additional substituents on the nitrogen are treated similarly to the case of amines: they are ordered alphabetically with the location prefix N: HCON(CH 3) 2 is N,N-dimethylmethanamide, CH 3 CON(CH 3) 2 is N,N-dimethylethanamide.
IUPAC nomenclature is used for the naming of chemical compounds, based on their chemical composition and their structure. [1] For example, one can deduce that 1-chloropropane has a Chlorine atom on the first carbon in the 3-carbon propane chain.
For the compound, SnO 2, the tin ion is Sn 4+ (balancing out the 4− charge on the two O 2− anions), and because this is a higher oxidation state than the alternative (Sn 2+), this compound is termed stannic oxide. Some ionic compounds contain polyatomic ions, which are charged entities containing two or more covalently bonded types of atoms ...
Article titles for compounds and related topics should reflect how the compound name is commonly written and use Greek letter prefixes if appropriate, e.g. Α-Ketoglutaric acid, using {{DISPLAYTITLE}} to display as α-Ketoglutaric acid, not Alpha-Ketoglutaric acid and displaying as alpha-Ketoglutaric acid.
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.
Whatever method is used, all polymer names have the prefix poly, followed by enclosing marks around the rest of the name. The marks are used in the order: {[( )]}. Locants indicate the position of structural features, e.g., poly(4-chlorostyrene). If the name is one word and has no locants, then the enclosing marks are not essential, but they ...
More structural information can be conveyed by adding the "structural descriptor" closo-, nido-, arachno-, hypho-, klado- prefixes. There is a fully systematic method of numbering the atoms in the boron hydride clusters, and a method of describing the position of bridging hydrogen atoms using the μ symbol.
Hydrates are ionic compounds that have absorbed water. They are named as the ionic compound followed by a numerical prefix and -hydrate. The numerical prefixes used are listed below (see IUPAC numerical multiplier): mono-di-tri-tetra-penta-hexa-hepta-octa-nona-deca-For example, CuSO 4 ·5H 2 O is "copper(II) sulfate pentahydrate".
