Lithium nitrate is an inorganic compound with the formula LiNO 3. It is the lithium salt of nitric acid (an alkali metal nitrate ). The salt is deliquescent , absorbing water to form the hydrated form, lithium nitrate trihydrate.
Even with this proviso, the electrode potentials of lithium and sodium – and hence their positions in the electrochemical series – appear anomalous. The order of reactivity, as shown by the vigour of the reaction with water or the speed at which the metal surface tarnishes in air, appears to be Cs > K > Na > Li > alkaline earth metals,
The nitrate ion. Alkali metal nitrates are chemical compounds consisting of an alkali metal (lithium, sodium, potassium, rubidium and caesium) and the nitrate ion. Only two are of major commercial value, the sodium and potassium salts. [1] They are white, water-soluble salts with melting points ranging from 255 °C (LiNO 3) to 414 °C (CsNO

Lithium nitrite is the lithium salt of nitrous acid, with formula LiNO 2. This compound is hygroscopic and very soluble in water. It is used as a corrosion inhibitor in mortar. [4] It is also used in the production of explosives, due to its ability to nitrosate ketones under certain conditions. [5]
The high lattice enthalpy of lithium fluoride is due to the small sizes of the Li + and F − ions, causing the electrostatic interactions between them to be strong: [5] a similar effect occurs for magnesium fluoride, consistent with the diagonal relationship between lithium and magnesium.
Carbamate group – Removed by acid and mild heating. Carbobenzyloxy (Cbz) group — Removed by hydrogenolysis: hydrogen and palladium on activated carbon, [50] or lithium or sodium in liquid ammonia. [51] p-Methoxybenzyloxycarbonyl (Moz or MeOZ) group – Removed by hydrogenolysis, more labile than Cbz
Here, a strong Lewis acid is required to generate either a carbocation from an alkyl halide in the Friedel-Crafts alkylation reaction or an acylium ion from an acyl halide. In the vast majority of cases, reactions that involve leaving group activation generate a cation in a separate step, before either nucleophilic attack or elimination.
