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 . Since enantiomeric pairs are the same chemical species, the different ... WebOct 22, 2014 · I didn't understand the fact that chiral objects are non-superimposable on their mirror images. I mean, if you put your right hand (apparently an achiral object) in front of a mirror, the mirror image will be like your left hand, but, when you make your hand touch the mirror, isn't it superimposable on its mirror image (and hence achiral)?
