The standard compound for determination of configuration in the 'sugar chemistry' is

The $\beta$ and $\alpha$ glucose have different specific rotations. When either is dissolved in water,their rotation changes until the same fixed value results. This is called:

The change in optical rotation with time of freshly prepared solutions of sugar is known as . . . . . . .

When $D^{-}$-glucose is treated with $Br_2$ water,the product is:

Assertion : Sucrose undergoes mutarotation.
Reason : Sucrose is a disaccharide.

What are monosaccharides?
