Glucose on reaction with $Br_{2}$ water gives

The change in specific rotation of glucose is due to which phenomenon?

Match List-$I$ with List-$II$:

List-$I$ $(\text{Saccharides})$	List-$II$ $(\text{Glycosidic linkages found})$
$(A)$ Sucrose	$(I)$ $\alpha 1-4$
$(B)$ Maltose	$(II)$ $\alpha 1-4$ and $\alpha 1-6$
$(C)$ Lactose	$(III)$ $\alpha 1-\beta 2$
$(D)$ Amylopectin	$(IV)$ $\beta 1-4$

Choose the correct answer from the options given below:

The optical rotation of the $\alpha$-form of a pyranose is $+150.7^{\circ}$,that of the $\beta$-form is $+52.8^{\circ}$. In solution,an equilibrium mixture of these anomers has an optical rotation of $+80.2^{\circ}$. The percentage of the $\alpha$-form in the equilibrium mixture is $....... \%$.
