WebApr 13, 2024 · Like molecules, solid crystals can exhibit mirror symmetry: the left and right forms are enantiomorphs. Enantiomorphism can occur even when the constituent molecules or ions are not chiral because they can pack together in a chiral pattern. Common quartz is a good example of a crystalline material with left and right … WebBoth the left and right hand are chiral (ky-ral) and show chirality. Chiral is derived from the Greek word cheir, which means “hand”, and chirality means “handedness”. Figure 5.3a Left hand and right hand are non-superimposable mirror images.
