A) racemisation
B) mutarotation
C) inversion
D) enolisation
Correct Answer: B
Solution :
The spontaneous change in the specific rotation of an optically active compound with time to an equilibrium value is called mutarotation. \[\underset{\begin{smallmatrix} specific\text{ }rotation \\ =+111{}^\circ \end{smallmatrix}}{\mathop{\alpha -Dglucose}}\,\underset{\begin{smallmatrix} specific\text{ }rotation \\ of\text{ }equilibrium \\ mixture\text{ }=\text{ }+52{}^\circ \end{smallmatrix}}{\mathop{open\text{ }chain\text{ }form}}\,\] \[\underset{\begin{smallmatrix} specific\text{ }rotation \\ =+19.2{}^\circ \end{smallmatrix}}{\mathop{\beta -D-glucose}}\,\]You need to login to perform this action.
