(a)
Interpretation:
The structure of the alditol should be identified and L-aldohexose gives the alditol when treated with sodium borohydride also should be identified.
Concept introduction:
Reduction:
Nitric Acid: Nitric acid oxidizes both the aldehyde and theterminal alcohol
To find: The D-aldopentose produces thealdaric acid
(b)
Interpretation:
The structure of the alditol should be identified and L-aldohexose gives the alditol when treated with sodium borohydride also should be identified.
Concept introduction:
Reduction: Aldehydes or ketones undergoing reduction by using reducing agent like LAH or NaBH4 which provides alcohol.
Nitric Acid: Nitric acid oxidizes both the aldehyde and theterminal alcohol
To find: Optically inactive alditols, when the D-aldopentoses treated with sodium borohydride
(c)
Interpretation:
The structure of the alditol should be identified and L-aldohexose gives the alditol when treated with sodium borohydride also should be identified.
Concept introduction:
Reduction: Aldehydes or ketones undergoing reduction by using reducing agent like LAH or NaBH4 which provides alcohol.
Nitric Acid: Nitric acid oxidizes both the aldehyde and theterminal alcohol
To find: synthesis of alditols as L-xylose
(d)
Interpretation:
The structure of the alditol should be identified and L-aldohexose gives the alditol when treated with sodium borohydride also should be identified.
Concept introduction:
Reduction: Aldehydes or ketones undergoing reduction by using reducing agent like LAH or NaBH4 which provides alcohol.
Nitric Acid: Nitric acid oxidizes both the aldehyde and theterminal alcohol
To find: The D-aldopentose can close into a β-pyranose (d).
