WebJul 19, 2024 · Chiral compounds are optically active molecules that are non-superimposable on their mirror images. Achiral compounds are optically inactive molecules that superimpose on their mirror images. However, meso compounds are optically inactive compounds with multiple chiral centers. 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.
