The difference is due to the spatial arrangement of different groups with different electronic configurations. Even though it wasn't specified in my textbook, I guess the difference Optical Activity - Chirality A carbon atom bddbonded to four diff tdifferent groups could ldlead toopti ltical acti ittivityand is called a stereogenic center. CH 3 CH 2CH 3 HO H In general organic compounds, which lack a plane of symmetry are optical active and are called chiral compounds. OH … Optical rotation, also known as polarization rotation or circular birefringence, is the rotation of the orientation of the plane of polarization about the optical axis of linearly polarized light as it travels through certain materials. Circular birefringence and circular dichroism are the manifestations of optical activity.Optical activity occurs only in chiral materials, those lacking Help understanding this passage on optical activity.
