How can i tell if a molecule is chiral
Web21 de dez. de 2015 · If a molecule has a centre of symmetry (i.e. inversion results in the identical molecule), a plane of symmetry or improper rotation (which is a rotation followed by mirroring along a plane orthogonal to the rotation axis) it is achiral. If you cannot find any of these symmetry elements, the molecule is chiral. Share Improve this answer Follow 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.
