The possible structures for (+)-mannose and (+)-glucose from the given pairs are to be chosen. Concept introduction: In chain extension reactions of aldoses, the carbon atom is added to the aldehyde group and forms sugars with one more carbon atom that the substrate. Molecules containing two identical chiral centers can be achiral. The stereo centers in the original sugar remain unaffected in chain extension reactions.

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.
