Question

C=O 2. Which of the following is an example of an aldopentose? Circle your answer. СН,ОН CH,он CH н-с-он H-6-H H-C-OH HO-C-H. H-C-H H-C-OH H-C-OH H-6-H H-C-OH CH,OH CH,OH CH OH 3. In the L- isomer of a Fischer projection of a monosaccharide, the -OH group furthest from the carbonyl is written. Circle your answer. on the left of the top chiral carbon. on the left of the middle chiral carbon. on the left of the bottom chiral carbon. on the right of the bottom chiral carbon 4. Classify as: aldo or keto; trio, tetro, pento, hexo; or none, the following compounds:

Answer 1

at we can use Buttom Instead of Furthest we can use too. L-isomer - mean-04 grout should be left side & this -Oh group will be at Bottom (Furthest from * So the correct Carbonyl on of the bottom chiral) the left Carbon Answer 4 - Hint Saccharide Containing s Aldo - - Keto - t=0 trio 7 = 3 tetoo tulno af (gp) these group should Be present in the Mono saccharides the mono saccharides Carbon Atom) Pento = hexo FG
