Chemistry - STEREO ISOMERISM Question with Solution | TestHub

Ans. Identical.

Sol. Both are cis-1,3-dimethylcyclopentane: in (a) both methyl groups are wedged (same face of the ring) and in (b) both are dashed (same face, ring viewed from the other side). Turning the molecule over interconverts the two drawings; cis-1,3-dimethylcyclopentane has a plane of symmetry and is achiral : identical.
