(a)
Interpretation:
The structures for the two salts that are produced when a racemic mixture of the acid molecule A is reacted with an enantiomerically pure chiral base B are to be drawn.
Concept introduction:
A racemic mixture is the one that has an equal amount of both enantiomers. When an acid is reacted with a base, a salt is produced. A mixture of salts is produced, when a racemic mixture of the acid molecule is treated with an enantiomerically pure base.
(b)
Interpretation:
Why the two salts produced in part (a) have different physical and chemical properties is to be explained.
Concept introduction:
A racemic mixture is the one that has an equal amount of both enantiomers. When an acid is reacted with a base, a salt is produced. When a racemic mixture of the acid molecule is treated with enantiomerically pure base, then a mixture of salts is produced. When two stereoisomers are related by the inversion of some, but not all, chiral centers, then the two molecules are diastereomers of each other. Diastereomers show different physical as well as chemical properties.
