Concept explainers
(a)
Interpretation:
Considering only the IUPAC names, the given pairs of molecules are to be identified as enantiomers, diastereomers, or neither.
Concept introduction:
A pair of configurational isomers can be identified as enantiomers or diastereomers on the basis of the R/S designation in the names of those molecules. If two stereoisomers have inverse configuration at each corresponding chiral center, they are enantiomers of each other. If two stereoisomers have inverse configuration at some, but not all corresponding chiral centers, they are diastereomers of each other.
(b)
Interpretation:
Considering only the IUPAC names, the given pairs of molecules are to be identified as enantiomers, diastereomers, or neither.

- PROBLEM Give IUPAC names for the following compounds. 4-28 (a) CH3 (b) H3C (c) н (e) H3C CH3 CH3 CH3 H (d) H Cara CH3 CH3 CH3arrow_forwardSee attached question.arrow_forwardQ2. Answer any TWO of the following parts: (a) Draw the two main conformations that exist for cyclohexane. Explain clearly why one conformer is more stable than the other. Using cis-1-ethyl-3-methylcyclohexane, as an example, explain how ring flipping occurs. Draw both conformers of cis-1-ethyl-3-methylcyclohexane and explain clearly which one predominates. (b) What is polarimetry? The specific rotation of (R)-carvone is - 61°. A chemist prepared a 750 mg mixture of (R)-carvone and its enantiomer in 10 ml of ethanol and placed the solution in a 10 cm polarimeter cell. The observed rotation was - 4.125°. Calculate the specific rotation for the above mixture. What is meant by enantiomeric excess? Then determine the % enantiomeric excess (% ee) in the mixture. (i) (ii) (iii) What % of the mixture is (R)-carvone and (S)-carvone?arrow_forward
- Problem: Perform a conformational analysis 2-iodo-2-methylbutane, looking down the C2—C3 bond. Pay attention to the relative energies of the various conformations, but do not concern yourself with the actual energy values. Pleae draw newman projections.arrow_forwardQuestion: which of the following molecules will have the greatest difference in energy between its chair conformations? I understand that both B and D have chair conformations that are more favored one way than another (B because it's cis 1-3 where both substituents are equatorial or axial and D because for monosubstituents there are 1-3 diaxial interaction if the substituent is axial position) but why is B greater than D? Is it due to the fact it is two substituents over one? Can you explain this for me?arrow_forwardProblem attachedarrow_forward
