The monosaccharide should be classified by the type of carbonyl group and the number of carbons in the chain. 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. 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.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
