To methyl α-D-mannopyranoside (methyl α-D-mannoside), Haworth projection and chair conformations has to be given and the anomeric carbon and the glycosidic bond has to be labelled. Concept Introduction: The aldehydes or ketones reacts with alcohol to form cyclic hemiacetal. If hemiacetal reacts with another alcohol molecule it forms acetal. Acetal is also known as glycoside. The bond formed between the anomeric carbon and the alcohol molecule is said to be glycosidic bond.

Question

b) Certain cyclic compounds are known to be conformationally similar to carbohydrates, although they are not themselves carbohydrates. One example is Compound C shown below, which could be imagined as adopting four possible conformations. In reality, however, only one of these is particularly stable. Circle the conformation you expect to be the most stable, and provide an explanation to justify your choice. For your explanation to be both convincing and correct, it must contain not only words, but also "cartoon" orbital drawings contrasting the four structures. Compound C Possible conformations (circle one): Дет

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.
