The products obtained from the isomers are alditols. Concept introduction: Both the isomers have aldehyde groups in open chain forms of carbohydrates and can be reduced to alcohol by sodium borohydride.

Question

Show the steps in converting Fischer to Haworth to: Convert D-Talose to its aIpha pyranose structure. Convert D-Tagatose to its beta furanose 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.
