Which one of the following concering the equilibrium shown is true ?

Options

A. The two structures are enantiomers of each other. They have equal but opposite optical rotations and recemic slowly at room temperature
B. The two structures are enantiomers of each other. They recemize too rapidly at room temperature for their optical rotations to be measured.
C. The two structures are diastereomers of each other. Their interconversion is called mutarotation
D. The two structures are diastereomers of each other. Their interconversion does not require breaking and making bonds, only a change in conformation

Answer

C

Explanation

`alpha-"D-glucose" overset("Mutarotation")hArr beta-"D-glucose"`
