Indira Gandhi National Open University, known as IGNOU, is a public open & distance learning university located in Delhi, India. Named after the former Prime Minister of India, Indira Gandhi, the university was established in 1985 with a budget of ₹ 20 million, after the Parliament of India passed the Indira Gandhi National Open University Act, 1985 (IGNOU Act 1985).

The following outline acts as an overview of and topical guide to chemistry: . Chemistry is the science of atomic matter (matter that is composed of chemical elements), especially its chemical reactions, but also including its properties, structure, composition, behavior, and changes as they relate to the chemical reactions.
The material is press-ready and may be printed by paying a 5% royalty, and by acknowledging NCERT. [11] The textbooks are in color-print and are among the least expensive books in Indian book stores. [11] Textbooks created by private publishers are priced higher than those of NCERT. [11]
[11] (R) or (S) is written in italics and parentheses. If there are multiple chiral carbons, e.g. (1R,4S), a number specifies the location of the carbon preceding each configuration. [12] The R/S system also has no fixed relation to the D/L system. For example, the side-chain one of serine contains a hydroxyl group, −OH.
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.
Chemical nomenclature is a set of rules to generate systematic names for chemical compounds.The nomenclature used most frequently worldwide is the one created and developed by the International Union of Pure and Applied Chemistry (IUPAC).
Forsterite. In chemistry, isomorphism has meanings both at the level of crystallography and at a molecular level. In crystallography, crystals are isomorphous if they have identical symmetry and if the atomic positions can be described with a set of parameters (unit cell dimensions and fractional coordinates) whose numerical values differ only slightly.
ACS Sustainable Chemistry & Engineering is a weekly peer-reviewed scientific journal published by the American Chemical Society. [1] [2] It covers research in green chemistry, green engineering, biomass, alternative energy, and life cycle assessment. [3] According to Journal Citation Reports, the journal has an impact factor of 7.1 in 2023. [4]
