Isopropyl alcohol (IUPAC name propan-2-ol and also called isopropanol or 2-propanol) is a colorless, flammable, organic compound with a pungent alcoholic odor. [9]Isopropyl alcohol, an organic polar molecule, is miscible in water, ethanol, and chloroform, demonstrating its ability to dissolve a wide range of substances including ethyl cellulose, polyvinyl butyral, oils, alkaloids, and natural ...

From left to right: the two isomeric groups propyl and 1-methylethyl (iPr or isopropyl), and the non-isomeric cyclopropyl group. In organic chemistry, a propyl group is a three-carbon alkyl substituent with chemical formula −CH 2 CH 2 CH 3 for the linear form.
The word's meaning became restricted to "spirit of wine" (the chemical known today as ethanol) in the 18th century and was extended to the class of substances so-called as "alcohols" in modern chemistry after 1850. [16] The term ethanol was invented in 1892, blending "ethane" with the "-ol" ending of "alcohol", which was generalized as a libfix ...
Two molecules (including polyatomic ions) A and B have the same structure if each atom of A can be paired with an atom of B of the same element, in a one-to-one way, so that for every bond in A there is a bond in B, of the same type, between corresponding atoms; and vice versa. [3]
The diisopropylbenzenes (DIPB) are organic compounds with the formula C 6 H 4 (CH(CH 3) 2) 2. Three isomers exist: 1,2- 1,3-, and 1,4-diisopropylbenzene. All are colorless liquids, immiscible in water, with similar boiling points. They are classified are aromatic hydrocarbons bearing a pair of isopropyl (CH(CH 3) 2) substituents. [1]
Huawei Technologies asked a U.S. judge to dismiss much of a federal indictment accusing the Chinese telecommunications company of trying to steal technology secrets from U.S. rivals and misleading ...
Polymer nomenclature usually applies to idealized representations meaning minor structural irregularities are ignored. A polymer can be named in one of two ways. Source-based nomenclature can be used when the monomer can be identified. Alternatively, more explicit structure-based nomenclature can be used when the polymer structure is proven.
