Cyclohexane stereochemistry

WebMeso compound. 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. [1] [2] This means that despite containing two or more stereocenters, the molecule is not chiral. A meso compound is "superimposable" on its mirror image (not to be confused with … WebAug 26, 2024 · So yes, rigidness of a ring due to stereochemistry does affect the number and type of signals. ... A similar effect can be observed in cyclohexane and derivatives, where cooling to low temperatures also freezes the ring flip and causes the signals of axial and equatorial protons to be distinct.
