Chemistry - STEREO ISOMERISM Question with Solution | TestHub

Compound (III) possesses a vertical Plane of Symmetry (P) passing directly through the C-1 and C-4 carbons, dividing the ring into two perfectly symmetrical halves. It exhibits Geometrical Isomerism (iii) because the rigid ring structure contains two substituted carbon centers (C-1 and C-4) that each carry two different chemical groups. Consequently, the combination (III) (iii) (P) is completely accurate and correctly details the properties of the molecule. Since the question asks for the only correct combination, Option (D) is the correct choice.
