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… WebDec 24, 2016 · This organic chemistry video tutorial explains difference between chiral molecules and achiral molecules and how to find them by drawing a line of symmetry. ... how do you choose your peers
