Chemistry - GOC Question with Solution | TestHub

There are 4 compounds that possess a Plane of Symmetry (POS): (ii), (iii), (vi), and (vii).

* (ii) contains a POS passing directly through the two substituted carbons and their attached atoms, bisecting the cyclobutane ring into two symmetrical halves.

* (iii) (bridged ring) and (vi) (unsubstituted chair cyclohexane) are inherently symmetric structures containing internal mirror planes.

* (vii) has a vertical POS that cuts perfectly between the two identical $Br$ groups and passes through the single methyl group.

* (i), (iv), (v), and (viii) lack any plane of symmetry due to their asymmetric or non-superimposable trans/dissymmetric geometry.
