(a)
Interpretation: The given disaccharide has to be classified as a reducing or non-reducing sugar.
Concept introduction: Monosaccharides and most of the disaccharides give positive test with Benedict’s solution. It is used to detect the presence of
(b)
Interpretation: The given disaccharide has to be classified as a reducing or non-reducing sugar.
Concept introduction: Monosaccharides and most of the disaccharides give positive test with Benedict’s solution. It is used to detect the presence of aldehyde or alpha hydroxy ketones. A positive test with Benedict’s solution is confirmed by the formation of a brick-red precipitate.

- Where are the chiral centers in this molecule? Also is this compound meso yes or no?arrow_forwardA mixture of C7H12O2, C9H9OCl, biphenyl and acetone was put together in a gas chromatography tube. Please decide from the GC resutls which correspond to the peak for C7,C9 and biphenyl and explain the reasoning based on GC results. Eliminate unnecessary peaks from Gas Chromatography results.arrow_forwardIs the molecule chiral, meso, or achiral? CI .CH3 H₂C CIarrow_forward
- A mixture of three compounds Phen-A, Acet-B and Rin-C was analyzed using TLC with 1:9 ethanol: hexane as the mobile phase. The TLC plate showed three spots of R, 0.1 and 0.2 and 0.3. Which of the three compounds (Phen-A; Acet-B or Rin-C) would have the highest (Blank 1), middle (Blank 2) and lowest (Blank 3) spot respectively? 0 CH: 0 CH, 0 H.C OH H.CN OH Acet-B Rin-C phen-A A A <arrow_forwardHow many chiral carbons are in the molecule?
