What is the reaction of n-butyllithium with ammonium chloride?
when nbutyl lithium is react with ammonium chloride gives LiCl and butane ,ammonia
What bases are the strongest?
In chemistry, a superbase is an extremely strong base. There is no commonly accepted definition for what qualifies as a superbase. In general, there are three main classes of superbases: organic, organometallic, and inorganic.In organic synthesis, the Schlosser base (or Lochmann-Schlosser base), i.e. the combination of tert-butyllithium and potassium tert-butoxide, is a commonly used superbase. tert-Butyllithium undergoes a cation exchange with potassium tert-butoxide giving tert-butyl potassium and lithium tert-butoxide, an exchange driven by lithium's affinity for the alkoxide oxygen. Replacement of the lithium cation with potassium causes the tert-butyl anion to acquire greater ionic character and thus greater basicity.Organometallic compounds of reactive metals are usually superbases, for example organolithium and organomagnesiums (Grignard reagents). Another type of organic superbase has a reactive metal exchanged for a hydrogen on a heteroatom, such as oxygen (unstabilized alkoxides) or nitrogen (lithium diisopropylamide).Inorganic superbases are typically salts with highly charged, small negative ions, e.g. lithium nitride, which has extreme negative charge density and so is highly attracted to acids, like the aqueous hydronium ion. Alkali and earth alkali metal hydrides (sodium hydride, calcium hydride) are superbases.

Does metal ions form molecules?
It depends on the definition of "molecule" and "metal". (Engineers tend to think of metal as things like, steel beams, brass, stainless steel, and things like that. To engineers, "metals" do not form molecules. They form just compounds.) However, in chemists' view--there are zillions of metal molecules in organometallics. Classic example is butyllithium. Lithium is actually covalently bonded to butane. Also there are many metalloproteins as well.

When exposed to air which chemical catches on fire but will not explode?
Such substances are called pyrophoric. Most are actually igniting in response to water vapour in the air, but it doesn't necessarily have to be that humid for them to start burning. On the list are, * iron sulfide; * depleted uranium (if sliced thinly or powdered); * other finely divided metals (including magnesium, calcium, zirconium) * Aakali metals (sodium, potassium) * metal hydrides or nonmetal hydrides (germane, diborane, sodium hydride, lithium aluminum hydride, uranium trihydride) * grignard reagents (compounds of the form RMgX) * fully or partially alkylated hydride derivatives(e.g., diethylaluminum hydride, trimethylaluminium, butyllithium, triethylboron) * alkylated metal alkoxides * nonmetal halides (diethylethoxyaluminum, dichloro(methyl)silane) * metal carbonyls (iron pentacarbonyl, dicobalt octacarbonyl, nickel carbonyl) * used hydrogenation catalysts, including Raney nickel (very volatile because of extra hydrogen already attached to it) * phosphorus (white, yellow) * plutonium * methanetellurol (CH3TeH)) Some gases are prone to such combustion, including * Arsine, Diborane, Phosphine, Silane, and the liquid hydrazine. Also metalorganic liquids. Some types of coal, caseium rubidium, silanes, and boiled linseed oil can also ignite when just exposed to ordinary air.
What is the strongest base listed on the pH scale?
There is no definite answer to this, but sec-Butyllithium can rip a proton from just about anything. A methanide compound (one with a C4- anion), in theory, would blow sec-Buyllithium out of the water. No one knows for sure what the strongest bases in the world are -spirit967
Which is the most strongest acid?
Corrected: pKa i.s.o. pHStrongest Acid: hexa-Fluoro-Antimonic Acid (HSbF6 or HF.SbF5), pKa = -25 Classified as a "Superacid". This acid will donate proton to C2H4 to form a ethane-carbocation. Compare: pKa(HClO4) = -10, HClO4 does not react with ethene.Strongest Base: Lithium Diisopropylamide [(CH3)2CH]2NLi ; pKb of 22. Classified as a "Superbase"; based upon greater than the alkalinity of pure NaOH (Sodium hydroxide, but LiOH is even stronger)Added: (s.o.a.)pH is a measure (or result) of the 'strength' (Ka) AND concentration [molarity] of an acid. But there is a limit to concentration of acid in water (solubility) AND the concentration of free (acidic) protons in water. That's why pH will never be much lower than -1.0 (proton concentration greater than 10.0 M rather impossible).Addendum: Although LDA is certainly a strong base, I wouldn't call it the strongest. Sodium amide, for example, has a pKa of 38, compared to 36 for LDA. Grignard reagents have even higher pKas, somewhere around 45, and there are likely stronger bases beyond that. Bear in mind, though, that these only apply to non-aqueous solutions; in water, the strongest acid which will exist is hydronium (H3O+), and the strongest base is hydroxide (HO-).
