Chemistry - STEREO ISOMERISM Question with Solution | TestHub

Ans. (A) No, because it has a centre of symmetry.

Sol. In this 1,3-dichloro-2,4-dibromocyclobutane, inversion through the centre of the ring maps each Cl onto the opposite Cl and each Br onto the opposite Br with wedge and dash interchanged exactly as drawn. A molecule with a centre of symmetry (COS) is achiral, so it is not optically active.
