6.1.1 Octant rule and its use in the study of unsaturated ketones

The carbonyl group of ketones has two planes of symmetry, and is therefore devoid of optical activity. Nevertheless, when the carbonyl group belongs to a molecule with one or more asymmetric carbons, optical activity is induced, which is observed in particular in the wavelength...
