To determine the given Haworth structure as the a or the ß form. Concept Introduction : D- Fructose is a monosaccharide with the chemical formula C 6 H 1 2 O 6 . A Haworth structure is a common way to write the structural formula of a given monosaccharide in the cyclic form with a simple 3-D perspective. The beta position in case of D-Fructose refers to the projection of -OH group on the same side on carbon number 6. This further results in upwards projection of hydroxyl group present on carbon number 2. Alpha configuration, on the other hand can be observed when there is downward projection of hydroxyl group on carbon number 2.

Concept Introduction :

D- Glucose is a monosaccharide with the chemical formula C₆H₁₂O₆. A Haworth structure is a common way to write the structural formula of a given monosaccharide in the cyclic form with a simple 3-D perspective. The beta position in case of D-glucose refers to the projection of -OH group on carbon no.1 above the plane of the ring Alpha configuration, on the other hand can be observed when there is downward projection of hydroxyl group on carbon No. 1.

A student proposes the transformation below in one step of an organic synthesis. There may be one or more reactants missing from the left-hand side, but there are no products missing from the right-hand side. There may also be catalysts, small inorganic reagents, and other important reaction conditions missing from the arrow. • Is the student's transformation possible? If not, check the box under the drawing area. . If the student's transformation is possible, then complete the reaction by adding any missing reactants to the left-hand side, and adding required catalysts, inorganic reagents, or other important reaction conditions above and below the arrow. • You do not need to balance the reaction, but be sure every important organic reactant or product is shown. + T X O O лет-ле HO OH HO OH This transformation can't be done in one step.
