Whether the carbohydrate D-mannose will produce a positive Benedict’s test or not. Introduction: On the basis of reactivity of carbohydrates, they can be classified as reducing and non-reducing sugars. The reducing sugars are those sugars in which free aldehyde or ketone group is present, which reacts with certain chemicals to reduce them. Non-reducing sugars lack free carbonyl group.

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.
