Ans. Diastereomers. Sol. Both Newman projections are 2,3-dibromobutane, CH 3 -CHBr-CHBr-CH 3 . In the first, identical groups are anti to each other (CH 3 /CH 3 , Br/Br and H/H): this is the achiral meso form, (2R,3S). In the second, the front centre is inverted - a chiral form, (2R,3R). Stereoisomers that are not mirror images : diastereomers.
