To determine: The enantiomers for the given structure, if possible.
Interpretation: The enantiomers for the given structure, if possible, are to be drawn.
Concept introduction: The two different forms in which a single chiral carbon can exist is referred to as enantiomers. The number of enantiomers of a molecule depends on the number of chiral centres. Enantiomers have opposite (R) and (S) configuration.

Both columns are packed with the same stationary phase, spherical particles with 1-um diameter. A) When the columns were prepared, the figure shows that the column with the larger diameter has more packing irregularities. Explain this observation. B) Predict what affect this should have on band broadening and discuss your prediction using the van Deemter terms. C) Does this figure support your explanations in application question 33? Explain why or why not and make any changes in your answers in light of this figure. Figure 4 SEM images of sections of packed columns for a) 750 and b) 30-um-i.d. capillary columns.³arrow_forward
