Chemistry - STEREO ISOMERISM Question with Solution | TestHub

In 2,6-dinitro-6'-fluoro-2'-carboxybiphenyl the two rings are held perpendicular by the bulky ortho substituents. The left ring carries identical NO₂ groups at its two ortho positions, so the plane of the right ring (σxy) bisects the left ring and reflects the two NO₂ groups into each other. The molecule has a plane of symmetry and is achiral (not resolvable).
