Optical active compounds
WebAnswer: Many diastereomers are optically active, but many are not. Explanation: By definition a diastereomer is any stereoisomer that is not an enantiomer Consider the possible optical isomers of 2,3-dichlorobutane. There are two chiral carbons, so there are 22 = 4 possible optical isomers. However, two of the structures are identical. WebApr 10, 2024 · This work revealed the structure of a reactive SmI2‒water complex for chemoselective reductive conversion of organic and inorganic compounds by in situ X-ray absorption spectroscopy. The water molecules assisted in the dissociation of the Sm‒I bond. View the article.
