Learn About the Preparation of Calcium Carbonate

Calcium Carbonate (CaCO3) is a white calcium salt with a chalky flavour that can be found in many foods. It is composed of the elements carbon, oxygen, and calcium, and it is insoluble in liquid water. It is possible to find pure carbon carbonate in minerals such as vaterite, aragonite, and calcite; however, vaterite is […]

Lanthanide

Lanthanides, also known as lanthanoids, are a group of metals with a high electropositive charge that reside between the s and d blocks of the periodic table. They’re also known as rare earth metals, with rarity referring to the difficulty of getting an element in its pure state, which has proven problematic due to the

Key Notes On History Of Halogens

Halogens are classified as nonmetals. Fluorine and chlorine are gases at room temperature, but bromine is a liquid at this temperature. Iodine and astatine are both solid substances. All of the halogens are extremely reactive, with the most reactive being fluorine, and the least reactive being astatine in nature . When it comes to nature,

IUPAC Nomenclature of Mononuclear Coordination Compounds

Coordination compounds are chemical compounds that consist of an array of anions or neutral molecules that are bound to a central atom via coordinate covalent bonds. These compounds are also known coordination complexes. These molecules  that are bound to the central atom are referred to as complexing agents or ligands. Important Points involved in Coordination

Isocyanide

Isocyanide  An organic compound with a group implied by the removal of an atom of hydrogen that can be combined with R – N+ ≡ C, is called isocyanide (also known as Isonitrile or Carbylamine). The nitrile isomers, known as nitrile isomers, were first synthesized in 1867 but have yet to see the wide-scale commercial

Importance of Diazonium Salts

The diazonium salts have the general formula R−N2+X−, where X is an organic or inorganic anion, and R is an alkyl or aryl group. They are organic compounds and contain two nitrogen atoms, one of which is positively charged. Diazonium salts are benzenediazonium chloride (C6H5N2+Cl–) and benzenediazonium hydrogen sulphate (C6H5N2+HSO4–). Importance of Diazonium Salts Used

Etard Reaction

The name “Etard” was inspired by French scientist Alexandre Léon Etard (1852 – 1910), who spent most of his career at Wurtz Laboratory. Using Etard reagent, also known as chromyl chloride, he found the partial oxidation of aromatic rings bearing methyl groups (CrO2Cl2). The Etard reaction uses Chromyl Chloride to partially oxidise aromatic ring-like Benzene.

Dinitrogen Trioxide, N2O3

Dinitrogen trioxide is prepared by mixing equal parts of nitric oxide and nitrogen dioxide. The temperature of NO2 is lowered to 21 degrees Celsius (6 degrees Fahrenheit). Only the liquid and solid states exist for this chemical. It produces a combination of NO and NO2 when heated. Commercially, Dinitrogen trioxide is made by oxidizing NO with air,
