(a)
Interpretation:
The structure of an aldotetrose should be drawn.
Concept Introduction:
Monosaccharides in which the carbonyl group is at C-1 position are
Monosaccharides can be classified by the number of carbons in the carbon chain.
3 C's − triose
4 C's − tetrose
5 C's − pentose
6 C's − hexose
In the classification of monosaccharides based on type of carbonyl group and number of carbons present in the chain, if the monosaccharide contains an aldehyde group, the prefix aldo- is added to the name and it is called an aldose. On the other hand, if a ketone group is present, it is a ketose or the prefix keto- is added.
(b)
Interpretation:
The structure of a ketopentose should be drawn.
Concept Introduction:
Monosaccharides in which the carbonyl group is at C-1 position are aldehydes and they are called aldoses. If the carbonyl group is at C-2 position are ketones and they are called ketoses.
Monosaccharides can be classified by the number of carbons in the carbon chain.
