(a)
Interpretation:
The structure of D-gluconic acid should be drawn
Concept introduction:
The Fischer projection: Fischer projection is a two-dimensional representation of a three-dimensional organic molecule by projection. It is mainly proposed for the representation of carbohydrate chemistry.
The orientation of the carbon atoms in a molecule is arranged vertically from top to bottom.
The C1 carbon is at the top of the orientation, the hydrogen and hydroxyl groups are placed in right and left side of the orientation. D and L form are depends on the arrangement of the hydroxyl group. If the hydroxyl group is in the right side of the molecule in the penultimate (next-to-last) carbon is called as D sugar, if the If the hydroxyl group is in the left side of the molecule in the penultimate (next-to-last) carbon is called as L sugar.
To find: The structure of D-gluconic acid.
(b)
Interpretation:
The structure of lactone should be drawn and the configuration at eachchirality center identified.
Concept introduction:
The Haworth projection: A Haworth projection is a three-dimensional representation of monosaccharides and the structural formula is inscription as a cyclic structures.
In Haworth projection, oxygen atom is placed in back right corner,
To find: The structure of lactone.
(c)
Interpretation:
The Optical activity of lactone should be identified.
Concept introduction:
Optical activity: molecule or substances that can rotate the plane-polarized light are said to be optically active.
To find: Optically activity of lactone.
(d)
Interpretation:
Difference between the D-gluconic acid and the lactone using IR Spectroscopy should be explained
Concept introduction:
Infra-red (IR) spectroscopy: Infra-red (IR) spectroscopy deals with the interaction between a molecule and radiation from the IR region of the
To find: Difference between the D-gluconic acid and the lactone using IR Spectroscopy.

- 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
