The chirality of a molecule is based on the molecular symmetry of its conformations. A conformation of a molecule is chiral if and only if it belongs to the Cn, Dn, T, O, I point groups (the chiral point groups). However, whether the molecule itself is considered to be chiral depends on whether its chiral conformations are persistent isomers that could be isolated as separated enantiomers, at least in principle, or the enantiomeric conformers rapidly interconvert at a given t… WebTests for chirality. (a) (Most reliable) Check to see if the molecule has a pair of non-superimposable mirror image forms. (b) (Nearly always works) Look for a mirror plane; if no mirror plane, the molecule is nearly always chiral. (c) Look for chiral centers – tetrahedral atoms (usually carbon) with four different groups attached.
