Although two chemical molecules may appear to have the same elements and similar properties, they can still have different structures. When two molecules appear identical and their structures differ only by being mirror images of each other, those molecules are said to have chirality. WebJul 1, 2024 · Tests 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. d2h android box
