Question
1 F1 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. 2 F2 W S #3 20 F3 E D S4 $ 4 F4 R LL % 5 F5 T G MacBook Air ^ 6 F6 Y & 7 H F7 U * 8 DII F8
