Vedclass · Answer

(D) Glucose exists in two anomeric forms: $\alpha$-$D$-glucose and $\beta$-$D$-glucose.When glucose is crystallized from a concentrated aqueous solution at $30 \ ^\circ C$,$\alpha$-$D$-glucose is obtained,which has a specific rotation of $+111^\circ$.When glucose is crystallized from hot glacial acetic acid,$\beta$-$D$-glucose is obtained,which has a specific rotation of $+19^\circ$.Therefore,the specific rotation of glucose crystals obtained from acetic acid is $19^\circ$.

The specific rotation of glucose crystals obtained by the crystallization of glucose in acetic acid is ......... $^o$.
