WebChirality and handedness are concepts that apply to the structure of molecules. Chirality is defined by the lack of certain features of symmetry, which lead to an object not being superimposable on its mirror image. Handedness is a different phenomenon relating to the ability to classify chiral objects into right-handed and left-handed objects. Webtwo versions of a chiral molecule are called "enantiomers". One is called "right-handed", and the other "left-handed". A shocking example of chirality Introduced in 1957 in West Germany, the drug Thalidomide was promoted for relief of morning sickness in pregnant women. A chiral compound, one enantiomer has the desired effect, while
