    The specific rotation of equilibrium mixture of \[\alpha -\]D-glucose and\[\beta -\] D-glucose, is:

    A)  \[+19{}^\circ \]                

    B) \[+112{}^\circ \]

    C)   \[+52{}^\circ \]                               

    D) \[+100{}^\circ \]

    Correct Answer: C

    Solution :

                     The specific rotation of \[\text{ }\!\!\alpha\!\!\text{ -D-}\]glucose is\[+113{}^\circ \]and that of \[\text{ }\!\!\beta\!\!\text{ -D-}\]glucose is\[+19{}^\circ \]. The specific rotation of their mixture, in equilibrium, is\[+52{}^\circ \].
