WebThis large collection of stereochemistry practice questions will test you on determining R/S configurations on chiral centers, to determine whether pairs of molecules are enantiomers, diastereomers or the same, identifying chiral molecules, and many more. These generally range from easiest at the top to more difficult at the bottom. WebApr 5, 2016 · A molecule is chiral when it doesn't exhibit any kind of symmetry. This particular molecule exhibits centre of inversion symmetry, i.e. it's symmetrical about a particular point. In this question that point is the midpoint of the bond joining the two substituted carbons.
