Stereochemistry - Chirality, Enantiomers

WebThe chiral compound contains an asymmetric center where the carbon is attached with four different atoms or groups. It forms two non-superimposable mirror images. What is meso compound in organic chemistry? A Meso compound or meso isomer is a non-optically active member of a set of stereoisomers, at least two of which are optically active. WebThis term derives from the Ancient Greek word “cheir” (χείρ) for hand, to give a pictorial sketch of the chirality meaning. In chemistry, molecules that feature chirality can be spatially arranged into two specular, nonsuperimposable structures called enantiomers .
