A possible synthesis of xylitol starting with appropriate monosaccharide is to be outlined. Concept introduction: Monosaccharides containing five carbon atoms and an aldehyde group are called aldopentoses. The compound xylose is an aldopentose and exists in both D − and L − forms . Alditols are the compounds produced from aldoses or ketoses on reduction with certain reducing agents, such as sodium borohydride ( NaBH 4 ) and hydrogen with a catalyst. Xylitol is an alditol and is used as a sweetener in chewing gums.

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.
