(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).

- Could you please solve the first problem in this way and present it similarly but (color-coded) and step by step so I can understand it better? Thank you! I want to see what they are doingarrow_forwardCan you please help mne with this problem. Im a visual person, so can you redraw it, potentislly color code and then as well explain it. I know im given CO2 use that to explain to me, as well as maybe give me a second example just to clarify even more with drawings (visuals) and explanations.arrow_forwardPart 1. Aqueous 0.010M AgNO 3 is slowly added to a 50-ml solution containing both carbonate [co32-] = 0.105 M and sulfate [soy] = 0.164 M anions. Given the ksp of Ag2CO3 and Ag₂ soy below. Answer the ff: Ag₂ CO3 = 2 Ag+ caq) + co} (aq) ksp = 8.10 × 10-12 Ag₂SO4 = 2Ag+(aq) + soy² (aq) ksp = 1.20 × 10-5 a) which salt will precipitate first? (b) What % of the first anion precipitated will remain in the solution. by the time the second anion starts to precipitate? (c) What is the effect of low pH (more acidic) condition on the separate of the carbonate and sulfate anions via silver precipitation? What is the effect of high pH (more basic)?
