Textbook Question
Chapter 19.9, Problem HQ
Intermediate G in Synthesis III is produced as a racemic mixture because
- 1. Chiral metal catalysts have not yet been developed by chemists.
- 2. Although 4-isobutylacetophenone is chiral, the stereochemical preferences for a particular enantiomeric product must coincidentally be near zero.
- 3. None of the reactants are chiral.
- 4. Answers 1 and 3 are correct.

Q
A
IR spectroscopy can be helpful in proving that limonene is optically active but it is not always necessary to
use IR spectroscopy in order to determine whether a molecule is optically active. Sometimes looking at the
molecule's physical properties can help to determine whether it is optically active.
3. If a sample is determined to be 75% of the (+) enantiomer, then what is the enantiomeric excess?
Answer question here
I
4. An experiment is performed were the specific rotation was determined to be +52° for the resulting
isolation (note this is not the observed rotation). If the enantiomerically pure compound has a literature
rotation of +97°, then what is the percent of each enantiomer in the isolated mixture?
Answer question here
5. Can you determine the percent R and S from the information given in questions 4? Explain.

Consider the reaction of (E)-hex-3-ene with HBr.
Draw the structures for (E)-hex-3-ene and the two major organic products for its reversion with HBr. Show all stereoisomers using wedge and dash stereochemistry at any chirality center
Please help with row 3 highlighted in yellow (column 1 and column 2); the instructions for the specific column in row 3 are above row 1:
Follow the instructions in each column. Hint for the last column: draw it with a wedge and again with adash – which gives the correct configuration?
