The name DuPhos is derived from the chemical company that developed this type of ligand (DuP, DuPont) and the compound class of phospholanes (Phos) it belongs to. FOOF: Dioxygen difluoride, O 2 F 2, an extremely unstable compound which reacts explosively with most other substances – the nickname "FOOF" is a play on its formula. [47] Furfuryl ...
Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [3] Notable examples include alkali metals, lithium through caesium, and alkaline earth metals, magnesium through barium.
Most chemical reactions take more than one elementary step to complete, and a reactive intermediate is a high-energy, hence unstable, product that exists only in one of the intermediate steps. The series of steps together make a reaction mechanism .
medium-lived fission product; probably most dangerous component of nuclear fallout Technetium-99: 43: 56: 210,000 y: β −: 294 Fission product: most common isotope of the lightest unstable element, most significant of long-lived fission products: Technetium-99m: 43: 56: 6 hr: γ,IC: 141 Synthetic: most commonly used medical radioisotope, used ...
Trifluoromethyl trifluoroethyl trioxide CF 3 OOOCF 2 CF 3 boils between 10 and 20° [142] Bis-trifluoromethyl carbonate boils between −10 and +10° [ 37 ] possibly +12, freezing −60° [ 143 ] Difluoroaminosulfinyl fluoride F 2 NS(O)F is a gas but decomposes over several hours [ 144 ]
Additionally, about 31 nuclides of the naturally occurring elements have unstable isotopes with a half-life larger than the age of the Solar System (~10 9 years or more). [ b ] An additional four nuclides have half-lives longer than 100 million years, which is far less than the age of the Solar System, but long enough for some of them to have ...
Nuclear chemistry is a sub-discipline of chemistry that involves the chemical reactions of unstable and radioactive elements where both electronic and nuclear changes can occur. The substance (or substances) initially involved in a chemical reaction are called reactants or reagents .
the simplest aldehyde; an important precursor to many other chemical compounds, such as polymers and polyfunctional alcohols Formic acid: the simplest carboxylic acid; often used as a source of the hydride ion Grignard reagents: the most common application is for alkylation of aldehydes and ketones: [4] Hexamethylphosphoramide
