If a monosaccharide contains a keto group,it is known as:

The number of chiral carbons present in sucrose is

How do you explain the absence of aldehyde group in the pentaacetate of $D$-glucose?

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

Reducing saccharides among the following are:

Sucrose	Ribose	Maltose	Lactose	Cellulose
$1$	$2$	$3$	$4$	$5$

Considering the facts that
$I$. sucrose forms glycosidic linkage between $C_1$ of glucose and $C_2$ of fructose,while
$II$. lactose forms glycosidic linkage between $C_1$ of galactose and $C_4$ of glucose.
Choose the correct statement.
