- Brønsted–Lowry acid is
defined as a
chemical substance that
protonates another substance. Upon
protonating a substrate, the m**** and the
charge of the species...

according to its
Hammett acidity function. It even
protonates some hydrocarbons to
afford pentacoordinate carbocations (carbonium...
-
superacids known to
protonate C60
fullerene without decomposing it. Additionally, they form stable,
isolable salts with
protonated benzene, C6H7+, the...
- the acid to
protonate alkanes,
which under normal acidic conditions do not
protonate to any extent. At 140 °C (284 °F), FSO3H–SbF5
protonates methane to...
- oldest-known
onium ion, and the
namesake for the class, is ammonium, NH+4, the
protonated derivative of ammonia, NH3. The name
onium is also used for
cations that...
- In chemistry,
methanium is a
complex positive ion with
formula [CH5]+ (metastable
transitional form, a
carbon atom
covalently bonded to five
hydrogen atoms)...
-
catalyze isomerization of
saturated hydrocarbons, and have been
shown to
protonate even weak bases,
including methane, xenon, halogens, and

- Dioxidanylium,
which is
protonated molecular oxygen, or just
protonated oxygen, is an ion with
formula HO+ 2. It is
formed when

conjugated enolates. When
those anions (but not the enol tautomer)
kinetically protonate, they do so at the
