Concept explainers
(a)
Interpretation:
To draw all the stereoisomers of (3S)-3-methylhexane when it is treated with Cl2
Concept introduction:
It is a chlorination reaction. The stereochemistry of the reaction depends mainly on whether the reaction occurs at a stereogenie center or any other atom, and whether a new stereogenic center is formed in it or not. An achiral starting material always gives either an achiral or a racemic product. But for the chiral, if a reaction does not occur at a stereogenic center, the configuration at a stereogenic center is retained in the product and if a reaction occurs at a stereogenic center, there is a mechanism to predict the stereochemistry of the product.
(b)
Interpretation:
To find out how many different fractions would be obtained from the isomers.

To find out how many fractions of the isomers would be optically active.

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_forward
