$C_{1}-C_{4}$ glycosidic bond is not found in

Sugar $X$:
$A.$ is found in honey.
$B.$ is a keto sugar.
$C.$ exists in $\alpha$ and $\beta$-anomeric forms.
$D.$ is laevorotatory.
$X$ 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:

Write the reactions of $D-Glucose$ which cannot be explained by its open-chain structure. How can the cyclic structure of glucose explain these reactions?

$A$ sugar '$X$' dehydrates very slowly under acidic conditions to give furfural,which on further reaction with resorcinol gives a coloured product after some time. Sugar '$X$' is

Identify the product formed when $D-(+)-glucose$ reacts with bromine water ($Br_2$ water).
