Chemistry - STEREO ISOMERISM Question with Solution | TestHub

Ans. Diastereomers.

Sol. Both are 2,3-dibromobutane. Reading the wedges and dashes: (a) is (2R,3S), the meso form (the two halves are mirror-related); (b) is (2R,3R), one of the chiral forms. A meso form and a chiral form are stereoisomers that are not mirror images : diastereomers.
