WebJan 23, 2024 · Chirality. Chirality essentially means 'mirror-image, non-superimposable molecules', and to say that a molecule is chiral is to say that its mirror image (it must have one) is not the same as it self. … WebSince the cis isomer has two centers of chirality (asymmetric carbons) but is achiral, it is a meso-compound. The corresponding trans isomers also exist as rapidly interconverting chiral conformations, but they are chiral. The diequatorial conformer predominates in each case, the (R,R) conformations being mirror images of the (S,S) conformations.
