Chemistry - STEREO ISOMERISM Question with Solution | TestHub

(A) Incorrect: Racemisation does not necessarily require breaking a bond to the chiral centre; it can occur through a planar intermediate.

(B) Correct: A racemate can be separated by resolution, whereas a meso/achiral compound cannot be resolved into enantiomers.

(C) Correct: Erythro → threo conversion involves a change in configuration at one stereogenic centre.

(D) Correct: D/L notation is unrelated to +/− rotation; a D-enantiomer can be dextrorotatory or levorotatory.

Hence, correct statements are B,C,D​
