Enantioselective synthesis, also called asymmetric synthesis, [1] is a form of chemical synthesis.It is defined by IUPAC as "a chemical reaction (or reaction sequence) in which one or more new elements of chirality are formed in a substrate molecule and which produces the stereoisomeric (enantiomeric or diastereomeric) products in unequal amounts."
Sajha Publications was established in 1913 (1970 BS) by the then-prime minister of Nepal, Chandra Shumsher as Gorkha Bhasa Prakashani Samiti (Gorkha Language Publishing Committee). It was renamed as Nepali Bhasa Prakashani Samiti (Nepali Language Publishing Committee) in 1933 (1990 BS). It was finally revamped as Sajha Prakashan in 1964
The aluminothermic reaction is used for the production of several ferroalloys, for example ferroniobium from niobium pentoxide and ferrovanadium from iron, vanadium(V) oxide, and aluminium.
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
Making a saline water solution by dissolving table salt in water.The salt is the solute and the water the solvent. In chemistry, a solution is defined by IUPAC as "A liquid or solid phase containing more than one substance, when for convenience one (or more) substance, which is called the solvent, is treated differently from the other substances, which are called solutes.
Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. [1]
Sajha Puraskar (Nepali: साझा पुरस्कार) is a literary award given by Sajha Publications. [2] It is presented annually to the best book published by Sajha Publication. History
2 co 2 + 12 h + + 12 e − → c 2 h 4 + 4 h 2 o −0.34 The redox potentials for these reactions are similar to that for hydrogen evolution in aqueous electrolytes, thus electrochemical reduction of CO 2 is usually competitive with hydrogen evolution reaction .
