They have the formula C 5 H 12–n Br n, where n = 1–12 is the number of bromine atoms. They are colorless liquids. ... 2-Bromopentane [1] (chiral) 3-Bromopentane;
Recognition status, as metalloids, of some elements in the p-block of the periodic table. Percentages are median appearance frequencies in the lists of metalloids. [n 2] The staircase-shaped line is a typical example of the arbitrary metal–nonmetal dividing line found on some periodic tables.
The only metal having an ionisation energy higher than some nonmetals (sulfur and selenium) is mercury. [citation needed] Mercury and its compounds have a reputation for toxicity but on a scale of 1 to 10, dimethylmercury ((CH 3) 2 Hg) (abbr. DMM), a volatile colourless liquid, has been described as a 15. It is so dangerous that scientists have ...
2-Bromopentane is a bromoalkane and isomer of bromopentane. It is a colorless liquid. 2-Bromopentane is chiral and thus can be obtained as either of two stereoisomers designated as ( R )-2-bromopentane and ( S )-2-bromopentane, or as a racemic 1:1 mixture of the two enantiomers .
Category is the word this Wikipedia uses for classifications in the metal-metalloid-nonmetal range. There is not any common word for it in the scientific world, and 'category' is not used for anything else. In the past, various sets of categories were used to colour in the periodic table, most recently: Metals Alkali metal Alkaline earth metal ...
Enantiotopic groups are identical and indistinguishable except in chiral environments. For instance, the CH 2 hydrogens in ethanol (CH 3 CH 2 OH) are normally enantiotopic, but can be made different (diastereotopic) if combined with a chiral center, for instance by conversion to an ester of a chiral carboxylic acid such as lactic acid, or if coordinated to a chiral metal center, or if ...
Individual, well-established "metallicity" categories, e.g. transition metal, post-transition metal, metalloid, rare earth metals etc., can be referred to without "all elements all once" colouring. When a specific categorisation scheme is relevant (e.g. {{ ChemicalBondsToCarbon }} ), a periodic table-filling categorisation can be applied.
