Organic redox reactions: the Birch reduction. Organic reductions or organic oxidations or organic redox reactions are redox reactions that take place with organic compounds.In organic chemistry oxidations and reductions are different from ordinary redox reactions, because many reactions carry the name but do not actually involve electron transfer.

The Chan–Lam coupling reaction, also known as the Chan–Evans–Lam coupling, is a cross-coupling reaction between an aryl boronic acid and an alcohol or an amine to form the corresponding secondary aryl amines or aryl ethers, respectively. [1] The Chan–Lam coupling is catalyzed by copper complexes. It can be conducted in air at room ...
Physical organic chemistry is the study of the relationship between structure and reactivity of organic molecules.More specifically, physical organic chemistry applies the experimental tools of physical chemistry to the study of the structure of organic molecules and provides a theoretical framework that interprets how structure influences both mechanisms and rates of organic reactions.
The organic ligands included are sometimes referred to as "struts" or "linkers", one example being 1,4-benzenedicarboxylic acid (BDC). More formally, a metal–organic framework is a potentially porous extended structure made from metal ions and organic linkers.
The Ho Chi Minh City University of Science (HCMUS; Vietnamese: Trường Đại học Khoa học Tự nhiên, Đại học Quốc gia Thành phố Hồ Chí Minh; formerly known as University of Sciences), or VNU-HCM University of Science, has offered various scientific degrees across Southern Vietnam since its establishment as the Indochina College of Science in 1941.
The HUS High School for Gifted Students, commonly known as High School for Gifted Students of Science (HSGS; Vietnamese: Trường Trung học phổ thông chuyên Khoa học Tự nhiên), is a specialized, most-selective (6% acceptance rate) public magnet school of VNU University of Science, a member of Vietnam National University, Hanoi system.
The main Vietnamese term used for Chinese characters is chữ Hán (𡨸漢).It is made of chữ meaning 'character' and Hán 'Han (referring to the Han dynasty)'.Other synonyms of chữ Hán includes chữ Nho (𡨸儒, literally 'Confucian characters') and Hán tự [a] (漢字) which was borrowed directly from Chinese.
The Vietnamese Wikipedia initially went online in November 2002, with a front page and an article about the Internet Society.The project received little attention and did not begin to receive significant contributions until it was "restarted" in October 2003 [3] and the newer, Unicode-capable MediaWiki software was installed soon after.
