Two sugars are epimers of each other. Is it possible to convert one to the other without breaking covalent bonds? Why? a) For chiral

Question

Two sugars are epimers of each other. Is it possible to convert one to the other without breaking covalent bonds? Why?
a) For chiral molecules with adjacent stereocenters, such as monosaccharides, a coordinated set of bond rotations can reverse th stereocenter.
b) For molecules with fourbr more stereocenters, the two epimers can interconvert by selected bond rotations
c) Rotation around bonds will not alter the chirality of a stereocenter )
d) A sing le rotation around each of two specific bonds of a stereocenter will alter the chirality at that stereocenter.

    Answer:

    Option c) is correct

    Explanation:

    No, it is not possible to convert one sugar to the other without breaking covalent bonds as rotation around bonds will not alter the chirality of a stereocenter.

    (A stereocenter refers to any point in a molecule that consists of various substituents, such that as two substituents are interchanged, it results in a stereoisomer.)

    Therefore,

    Option c) is correct
