Which of the following statements is true for a pair of diastereomers ...
Diastereomers
Diastereomers are stereoisomers that are not mirror images of each other and have different physical and chemical properties. They are formed when a molecule has two or more stereocenters and there is a different spatial arrangement of substituents around these stereocenters.
Different Physical Properties
Diastereomers have different physical properties such as boiling points, melting points, solubilities, densities, and refractive indices. This is because the spatial arrangement of substituents in diastereomers leads to different intermolecular forces and interactions between molecules. These differences in physical properties make it possible to separate diastereomers using techniques such as column chromatography or fractional distillation.
Identical Chemical Properties
Unlike enantiomers, which have identical chemical properties except for their interaction with plane-polarized light, diastereomers have different chemical properties. The spatial arrangement of substituents in diastereomers leads to different steric effects, which can affect their reactivity. Diastereomers may have different rates of reaction, selectivity in chemical reactions, or different products formed in chemical reactions.
Specific Rotations of Opposite Sign
The specific rotation is a measure of the rotation of plane-polarized light by a chiral compound. Enantiomers have the same magnitude of specific rotation but opposite signs. Diastereomers, on the other hand, can have different magnitudes and signs of specific rotation. Therefore, statement b) is incorrect.
Therefore, the correct answer is option d) They will have different physical properties. Diastereomers have different physical properties due to their different spatial arrangements, while they have identical or similar chemical properties.
