The six-membered ring structures of D-glucose has to be drawn. Concept introduction: Glucose is a monosaccharide with a molecular formula C 6 H 12 O 6 . It can exist both as an open-chain structure and a cyclic structure. It has 16 aldohexose stereoisomers and D-glucose is one of them. It occurs more widely in nature than L-glucose. The intramolecular nucleophilic addition reaction between the aldehyde group and hydroxyl group forms a hemiacetal linkage which results in the cyclic ring structure.

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.
