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.

WebMolecules with a single chirality centre are chiral. Molecules with more than one chirality centre are usually chiral. The exceptions are meso compounds. For example, tartaric acid has two chirality centres, so you would expect it to have #2^2 = 4# stereoisomers. But there are only three isomers.
