How to identify a compound as chiral or achiral

Web26 de mar. de 2016 · Any molecule that contains a chiral center will be chiral, with one exception: a meso compound. A meso compound contains a plane of symmetry and so is achiral, regardless of whether the molecule has a chiral center. A plane of symmetry is a plane that cuts a molecule in half, yielding two halves that are mirror reflections of each … Web(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.
