A) epimerization
B) racemization
C) anomerization
D) mutarotation
E) inversion
Correct Answer: D
Solution :
The\[\beta \]and\[\alpha -\]glucose have different specific rotations. When either is dissolved in water, their rotation changes until the same fixed value results. This is called mutarotation. \[\underset{Specific\text{ }rotation=+111{}^\circ }{\mathop{\alpha -D-glucose}}\,\underset{\begin{smallmatrix} specific=+52.5{}^\circ \\ of\text{ }equilibrium\text{ }mixture \end{smallmatrix}}{\mathop{open\,chain\,form}}\,\] \[\underset{specific\text{ }rotation=+19.2{}^\circ }{\mathop{\beta -D-glucose}}\,\]
