In chemistry, an oxonium ion is any cation containing an oxygen atom that has three bonds and 1+ formal charge. [1] The simplest oxonium ion is the hydronium ion (H 3 ...
In chemistry, hydronium (hydroxonium in traditional British English) is the cation [H 3 O] +, also written as H 3 O +, the type of oxonium ion produced by protonation of water.It is often viewed as the positive ion present when an Arrhenius acid is dissolved in water, as Arrhenius acid molecules in solution give up a proton (a positive hydrogen ion, H +) to the surrounding water molecules (H 2 O).
Oxatriquinane (oxoniaperhydrotriquinacene) is an alkyl oxonium ion with formula (CH 2 CH 2 CH) 3 O +. It has a cyclononane backbone, with a tricoordinated oxygen connected to carbon 1, 4, and 7, forming three fused pentagonal rings. In contrast to most trialkyloxonium ions, oxatriquinane hydrolyzes slowly.
Oxonium may refer to: . Oxonium ion, any ion which contains a tricoordinated oxygen atom, RR'R"O +; Oxonium, an IUPAC name for the simplest oxonium ion, hydronium, H 3 O + Oxonium (often abbreviated to Oxon.), sometimes used in university circles as a Latin name for Oxford University in England
For example, from a solution of tetrachloroauric acid, the oxonium ion [H 7 O 3] + has been isolated as the salt [(H 7 O 3)(15-crown-5) 2][AuCl 4]. Neutron diffraction studies revealed a sandwich structure, which shows a chain of water with remarkably long O-H bond (1.12 Å) in the acidic proton, but with a very short OH•••O distance (1. ...
Oxatriquinacene is an organic cation with formula C 9 H 9 O +It is an oxonium ion, with a tricoordinated oxygen atom with +1 charge connected to carbons 1,4, and 7 of a cyclononatriene ring, forming three fused pentagonal cycles.
Triethyloxonium tetrafluoroborate is the organic oxonium compound with the formula [(CH 3 CH 2) 3 O] + [BF 4] −. It is often called Meerwein's reagent or Meerwein's salt after its discoverer Hans Meerwein. [2] [3] Also well known and commercially available is the related trimethyloxonium tetrafluoroborate. The compounds are white solids that ...
Oxygen-14 is the second most stable radioisotope. Oxygen-14 ion beams are of interest to researchers of proton-rich nuclei; for example, one early experiment at the Facility for Rare Isotope Beams in East Lansing, Michigan, used a 14 O beam to study the beta decay transition of this isotope to 14 N.
