This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment. Chemistry is a physical science concerned with the composition, structure, and properties of matter , as well as the changes it undergoes during chemical reactions ...
The shorter of the two chains becomes the first part of the name with the -ane suffix changed to -oxy, and the longer alkane chain becomes the suffix of the name of the ether. Thus, CH 3 OCH 3 is methoxymethane, and CH 3 OCH 2 CH 3 is methoxyethane (not ethoxymethane). If the oxygen is not attached to the end of the main alkane chain, then the ...
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').
The main structure of chemical names according to IUPAC nomenclature. IUPAC nomenclature is a set of recommendations for naming chemical compounds and for describing chemistry and biochemistry in general. The International Union of Pure and Applied Chemistry (IUPAC) is the international authority on chemical nomenclature and terminology.
New names were provided in both French and Latin for the benefit of an international readership. For a modern reader these dictionaries are still useful, but now to discover and understand older names, rather than the new. In the English version, [16] the new names had been adapted to English, though they did not always align with current ...
The names of the saturated hydrides of non-metals end with the suffix -ane: the hydrides of silicon are called silanes (SiH 4); the hydrides of boron are boranes (B 2 H 6). The final "-e" is dropped before a suffix that starts with a vowel, e.g. "propanol". [1] Alternatively, "-ane" may be used for a mononuclear hydride of an element.
The suffix is also used more generally in English to form adjectives from nouns, with the sense "full of", [2] as in "verbose": wordy, full of words. Monosaccharides , the simplest sugars, may be named according to the number of carbon atoms in each molecule of the sugar: pentose is a five-carbon monosaccharide, and hexose is a six-carbon ...
The recommendations take up over 300 pages [1] and the full text can be downloaded from IUPAC. [2] Corrections have been issued. [3] Apart from a reorganisation of the content, there is a new section on organometallics and a formal element list to be used in place of electronegativity lists in sequencing elements in formulae and names. The ...
