(a)
Interpretation:
A curved-arrow mechanism for the given reaction is to be drawn.
Concept introduction:
The Edman degradation is a process to identify the amino acid sequence in a peptide. In this process, the residue of amino-terminal is labeled and cleaved from peptide and the other peptide bonds present between the other amino acid residues do not get disturbed.
Phenyl isothiocynate is known as edman reagent. The reaction is helpful for the
(b)
Interpretation:
A curved-arrow mechanism for the given reaction is to be drawn.
Concept introduction:
The nucleophilic substitution reactions are the reactions in which nucleophile attack at the electrophilic carbon. These reactions depend upon the nucleophilicity and concentration of the nucleophile.
The Edman degradation is a process to identify the amino acid sequence in a peptide. In this process, the residue of amino-terminal is labeled and cleaved from peptide and the other peptide bonds present between the other amino acid residues do not get disturbed.

- PLEASE HELP! URGENT!arrow_forwardWhere 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_forward
- How many chiral carbons are in the molecule? OH F CI Brarrow_forwardA 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?
