Chemistry - STEREO ISOMERISM Question with Solution | TestHub

(A) 2,3-Dibromopentane → 2 chiral centres, no symmetry → 4 optical isomers → 3

(B) Tartaric acid → 2 chiral centres with meso form → 2 active + 1 meso = 3 → 1,2

(C) Lactic acid → 1 chiral centre → 2 optically active isomers → 1

(D) HOOC–CHOH–CHOH–CHOH–COOH → 3 chiral centres with symmetry → meso present → 1,3,4
