The Fischer projection of D-Allose and L-Allose are needed to be determined if the four chirality centers of D-Allose are in R-configuration. Concept introduction: Fischer projection of carbohydrates are drawn by vertical line representing the cyclic carbon chain and the attached OH and H groups are placed in right or left side of each carbon atoms. The position of carbonyl group is on top of the line. R and S configuration of chiral carbons of carbohydrates are depending upon the location of –OH groups on the each carbon atom in Fischer projection. If the –OH group is in right side then, the configuration is R . If the –OH group is in left side then, the configuration is S . D and L configuration of a sugar are Enantiomers. Enantiomers are non-super imposable mirror images of each other. To draw: the Fischer projection of D-Allose, if the four chirality centers of D-Allose are in R-configuration.

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.
