Question
Chapter 5.4, Problem 15PTS
Interpretation Introduction
Interpretation:
To calculate the enantiomeric excess (ee) of given molecules.
Concept Introduction:
Enantiomeric excess: The (ee) is a measurement of purity for chiral substances, and its reflected the degree to which a sample contains one enantiomer in greater amounts then the other.
Consider for simple example the d-enantiomers (75%) exceeds the percentage of the l-enantiomers (25%) and (ee) of compound 50%.
To identify: The given molecules enantiomeric excess (ee) should be identified.

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.
