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 ...
In the modern IUPAC nomenclature, this group is known as group 17. [5] The word "halogen" means "salt former" or "salt maker". When halogens react with metals, they produce a wide range of salts, including calcium fluoride, sodium chloride (common table salt), silver bromide and potassium iodide.
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 ...
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 ...
Hemoglobin helps red blood cells carry oxygen to your muscles and tissues. Abnormal hemoglobin levels can be a sign of several health problems. Hemoglobin is a component of your blood that ...
Haloacetic acids. Haloacetic acids or HAAs are carboxylic acids in which one or more halogen atoms take the place of hydrogen atoms in the methyl group of acetic acid. Those acids have a general chemical formula X 1X2X3 C −C O 2 H, where X is hydrogen or halogen, and at least one X is a halogen. In a monohaloacetic acid ( XCH2−CO2H ), a ...
RXNO:0000689. 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 ...
