Cryptochirality
Webcryptochirality ( uncountable ) ( chemistry) A form of chirality in which the properties of the pair of chiral compounds are indistinguishable 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 is the specific electronic properties of the molecule. The term was introduced by …
