Chemistry - STEREO ISOMERISM Question with Solution | TestHub

Ans. (D) 0.

Sol. The central carbon bears H and three identical -CH(F)Br arms, so the molecule has three stereocentres on a C₃-symmetric skeleton. The configurations fall into two sets: (R,R,R)/(S,S,S) and (R,R,S)/(S,S,R); each set is an enantiomeric pair. No configuration is achiral, so the number of meso isomers = 0.
