Chemistry - STEREO ISOMERISM Question with Solution | TestHub

Ans. Diastereomers.

Sol. Both Newman projections are CH₃-C(Cl)(Br)-C(Cl)(Br)-CH₃ (2,3-dibromo-2,3-dichlorobutane, two stereocentres). Assigning configurations from the projections: the first is (2S,3S), a chiral form; the second is (2R,3S), the meso form. Stereoisomers that are not mirror images : diastereomers.
