WebCryptochirality in stereochemistry is a special case of chirality where due to the electronic properties of the chiral molecule its specific rotation is non-measurable. The term was introduced by K. Mislow in 1977. For example the alkane 5-ethyl-5-propylundecane found in certain species of Phaseolus vulgaris has two enantiomeric forms without any … WebIn stereochemistry, cryptochirality is a special case of chirality in which a molecule is chiral but its specific rotation is non-measurable. The underlying reason for the lack of rotation …
