Halogenation. In chemistry, halogenation is a chemical reaction which introduces of one or more halogens into a chemical compound. Halide -containing compounds are pervasive, making this type of transformation important, e.g. in the production of polymers, drugs. [1] This kind of conversion is in fact so common that a comprehensive overview is ...
The chemical reactivity of halogen atoms depends on both their point of attachment to the lead and the nature of the halogen. Aromatic halogen groups are far less reactive than aliphatic halogen groups, which can exhibit considerable chemical reactivity. For aliphatic carbon-halogen bonds, the C-F bond is the strongest and usually less ...
Website. hshs.org. Hospital Sisters Health System, or HSHS, is a non-profit healthcare system headquartered in Springfield, Illinois. HSHS operates a network of 15 hospitals and other healthcare facilities throughout the midwestern U.S. states of Illinois, and Wisconsin. HSHS also operates St. John's College, the oldest Catholic hospital based ...
Halogen bond. In chemistry, a halogen bond ( XB) occurs when there is evidence of a net attractive interaction between an electrophilic region associated with a halogen atom in a molecular entity and a nucleophilic region in another, or the same, molecular entity. [1] Like a hydrogen bond, the result is not a formal chemical bond, but rather a ...
Interhalogen. In chemistry, an interhalogen compound is a molecule which contains two or more different halogen atoms ( fluorine, chlorine, bromine, iodine, or astatine) and no atoms of elements from any other group. Most interhalogen compounds known are binary (composed of only two distinct elements).
A statement released by HSHS Monday said that MyChart communication, which helps patients schedule, manage, and check in for appointments; message care teams; pay bills; get test results and after ...
Electrophilic halogenation. In organic chemistry, an electrophilic aromatic halogenation is a type of electrophilic aromatic substitution. This organic reaction is typical of aromatic compounds and a very useful method for adding substituents to an aromatic system. A few types of aromatic compounds, such as phenol, will react without a catalyst ...
In chemistry, the haloform reaction is a chemical reaction in which a haloform ( CHX3, where X is a halogen) is produced by the exhaustive halogenation of an acetyl group ( R−C (=O)CH3, where R can be either a hydrogen atom, an alkyl or an aryl group ), in the presence of a base. [1] [2] [3] The reaction can be used to transform acetyl groups ...
