Stereospecificity of reaction between olefin and hypobromous acid(HOBr) in base, N-bromosuccinimide(NBS), is determined by the formation of a bromonium intermediate; the electrophilic bromonium cation approaches the ring's less sterically hindered α-face and is attacked by the π-electron density of the alkene.
of which the quantum harmonic oscillator, the particle in a box, the dihydrogen cation, and the hydrogen atom are the most important representatives.
is only known in one cation, IrO+ 4; it is only known as gas-phase species and is not known to form any salts.
However, the simultaneous exchange of cations and anions can be more efficiently performed in mixed beds that contain a mixture of anion and cation exchange resins, or passing the treated solution through several different ion exchange materials.
ν is the number of ions in the empirical formula, z+ and z- are the numbers of elementary charge on the cation and anion, respectively, and r+ and r- are the radii of the cation and anion, respectively, in meters.
she proposed the name catium(Cm) for her newly discovered element, as she believed it to be the most electropositive cation of the elements.
raising the calcium level, mainly by increasing calcium absorption from food, mobilising bone-matrix-fixed calcium into ionised form(mainly monohydrogencarbonate calcium cation, partially bound to plasma proteins,[CaHCO3]+),
This is described in more detail under potassium ferrioxalate. Theoretically the two stereoisomers could be separated by crystallization of a diastereomeric salt of the optically inactive racemic mixture of ferrioxalate ions with an optically active cation, such as methylethylpropylammonium ion which is one pure enantomer.
NASA astronaut John Glenn was issued with benzylamine hydrochloride for this purpose for the Mercury-Atlas 6 mission.[29] The cation in this salt is called benzylammonium and is a moiety found in
become permeable to cations, most particularly the calcium cation; this evokes a powerful irritant effect followed by desensitization and analgesia.
He and fellow investigators found that the soils macaws choose to consume at the clay licks do not have higher levels of cation exchange capacity(ability to absorb toxins) than that of unused areas of the clay licks
one Zn(2) cation, whereas the apical OH groups[O(2)H]
One way to remember the definitions of cations and anions is to think of the letter"t" in the word cation as looking like a plus symbol.
Cations need not be metal ions, but can be any positively-charged ion,
Ammonium fluoride adopts the wurtzite crystal structure, in which both the ammonium cations and the fluoride anions are stacked in ABABAB….
structure of potassium chloride(KCl), a salt which is formed due to the attraction of K+ cations and Cl- anions.
The scope of HPLC is very limited for analyses of standard anions, cations, organic acids, and sugars in water and various foods.
A and B are cations, whilst X represents an anion, which bonds to both.
18 sodium cations, and 15 molecules of water,
Ion exchange resins are used to exchange non desirable cations and anions with hydrogen and hydroxyl, respectively,
