Vedclass · Answer

(C) The process of mutarotation involves the interconversion of $\alpha-D-$glucose and $\beta-D-$glucose in an aqueous solution until an equilibrium is reached.$\alpha-D-$glucose has a specific rotation of $+112^o$.$\beta-D-$glucose has a specific rotation of $+19^o$.At equilibrium,the mixture contains approximately $36\%$ of $\alpha-D-$glucose and $64\%$ of $\beta-D-$glucose.The specific rotation of the equilibrium mixture is calculated as: $(0.36 	imes 112^o) + (0.64 	imes 19^o) \approx 40.32^o + 12.16^o = 52.48^o \approx +52^o$.

The specific rotation of the equilibrium mixture of $\alpha-D-$glucose and $\beta-D-$glucose is ......... $^o$.
