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.

It is D sugar the molecule is a retrose. Elclose or eldotetrose, is 4-carbon elclose.

Explanation of Solution

Concept strategy: The Fischer projection of the given monosaccharide is drawn vertically, by rotating the molecule anticlockwise 90° so that the carbonyl aldehyde -CHO group is vertically at the top and the CH₂OH group is at the bottom. [The red balls represent oxygen atoms, the black balls represent carbon atoms, and each smell white ball represents hydrogen]. The intention –H and –OH are drawn to the sides, pointing art of the page towards the review. Thus the given model becomes

Organic Chemistry, Chapter 25.SE, Problem 26VC , additional homework tip 3

Explanation of Solution

By convention, the terminal -CH₂OH group is on the top of the chair Pyranose structure. Thus it is a D sugar. The molecule is an aldohexose is B-D-glucopyranose, all the –OH groups are equatorial (and more stable due to minimum repulsion) conformation.

Conclusion

Based on the Fischer projection formula for the given sugars it is a B-D-glucopyranose monosaccharide.
