Chemistry - STEREO ISOMERISM Question with Solution | TestHub

Ans. Enantiomers.

Sol. The ball-and-stick model is CH₃-CH(Br)-CH₂-CH₃ (2-bromobutane; large sphere = Br). The Fischer projection is also 2-bromobutane (Br left, H right, i.e. the R form with priorities Br $>$ C₂H₅ $>$ CH₃ $>$ H); the model shows the opposite configuration. One stereocentre, opposite configurations : enantiomers.
