WebMay 10, 2015 · 11. Look for carbons with four different groups attached to identify potential chiral centers. Draw your molecule with wedges and dashes and then draw a mirror image of the molecule. If the molecule in the mirror image is the same molecule, it is achiral. If they are different molecules, then it is chiral. 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.
