Chemistry - STEREO ISOMERISM Question with Solution | TestHub

Ans. Enantiomers.

Sol. Both Newman projections are CH(OH)(Cl)-CH(OH)(Cl) (two stereocentres). On the front carbon OH, H and Cl are all interchanged by a mirror reflection, and the same holds for the back carbon, so BOTH centres are inverted. The first is (2R,3R) and the second is (2S,3S) : non-superimposable mirror images : enantiomers.
