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

Consider the following SN 2 reaction: مار + Br H₂O acetone + Br OH What effect would each of the following changes have on the rate of this reaction. Select the single best answer for each part. Part 1 of 3 If the substrate was changed to: The rate would Br O increase O decrease O remain unchanged Part 2 of 3 × S If the nucleophile was changed to OH, the rate would: O increase O decrease O remain unchanged Part 3 of 3 If the solvent was changed to ethanol, the rate would: Increase O decrease O remain unchanged 2 ol Ar

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.
