(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.

- 4. Draw and label all possible isomers for [M(py)3(DMSO)2(CI)] (py = pyridine, DMSO dimethylsulfoxide).arrow_forwardThe emission data in cps displayed in Table 1 is reported to two decimal places by the chemist. However, the instrument output is shown in Table 2. Table 2. Iron emission from ICP-AES Sample Blank Standard Emission, cps 579.503252562 9308340.13122 Unknown Sample 343.232365741 Did the chemist make the correct choice in how they choose to display the data up in Table 1? Choose the best explanation from the choices below. No. Since the instrument calculates 12 digits for all values, they should all be kept and not truncated. Doing so would eliminate significant information. No. Since the instrument calculates 5 decimal places for the standard, all of the values should be limited to the same number. The other decimal places are not significant for the blank and unknown sample. Yes. The way Saman made the standards was limited by the 250-mL volumetric flask. This glassware can report values to 2 decimal places, and this establishes our number of significant figures. Yes. Instrumental data…arrow_forwardSteps and explanation pleasearrow_forward
