The number of chiral carbons in $\beta-D-(+)$-glucose is

In fermentation by zymase,alcohol and $CO_2$ are obtained from which of the following sugars?

When sugar $X$ is boiled with dilute $H_{2}SO_{4}$ in an alcoholic solution,two isomers $A$ and $B$ are formed. $A$ on oxidation with $HNO_{3}$ yields saccharic acid,whereas $B$ is laevorotatory. The compound $X$ is ....... .

Natural glucose is termed $D$-glucose because

The hydrolysis of sucrose produces a mixture which is:
