Question

Diastereomers and Meso Forms For any molecule that has two or more chiral centers, it is possible to have stereoisomers that are not mirror images. Stereoisomers that are not related as enantiomers are diastereomers. Diastereomers differ in all properties, chiral and achiral Procedure: Construct a model with four different groups (light blue ball, blue, red, and green) attached to a central carbon atom (black). Construct another model identical to the first. (Be sure they are identical by making sure the models are superimposable.) Now remove the green substituent from each model and connect the two carbon atoms with a bond.Use this model with the two stereogenic centers for the next series of questions (14-26)

Explanation / Answer

16.Mirror images are not identical.

Therefore option (b) is correct.

17.The above are non superimposable mirror images so they are known as enantiomers.

Therefore option (a) is correct.

18.They must contain a chital centre.

So option (a) is correct.
