Chemistry - STEREO ISOMERISM Question with Solution | TestHub

In 2,6-dichloro-6'-fluoro-2'-nitrobiphenyl the two rings are held perpendicular by the bulky ortho substituents. The left ring carries identical Cl atoms at its two ortho positions, so the plane of the right ring (σxy) bisects the left ring and reflects the two Cl atoms into each other. The molecule has a plane of symmetry and is achiral (not resolvable).
