Curved arrow notation and the products for all elimination steps are to be drawn, and the major product from all products is to be predicted. Concept introduction: In the nucleophilic elimination step, the more electronegative atom bears full negative charge or partial negative charge. This is the electron rich atom, and the less electronegative atom bonded to an electronegative atom is relatively electron poor. The curved arrow is drawn from the lone pair of electron rich atom points to the bonding region between the more electronegative atom and less electronegative atom representing the electron flow from electron rich site to electron poor site. The second curved arrow is drawn to represent the breaking of bond between the less electronegative atom and the leaving group to avoid exceeding an octet on the less electronegative atom. If the leaving group is a stable ion species, the product is a major product.

Interpretation Introduction

Interpretation:

Curved arrow notation and the products for all elimination steps are to be drawn, and the major product from all products is to be predicted.

Concept introduction:

In the nucleophilic elimination step, the more electronegative atom bears full negative charge or partial negative charge. This is the electron rich atom, and the less electronegative atom bonded to an electronegative atom is relatively electron poor. The curved arrow is drawn from the lone pair of electron rich atom points to the bonding region between the more electronegative atom and less electronegative atom representing the electron flow from electron rich site to electron poor site. The second curved arrow is drawn to represent the breaking of bond between the less electronegative atom and the leaving group to avoid exceeding an octet on the less electronegative atom.

If the leaving group is a stable ion species, the product is a major product.

(a 4 shows scanning electron microscope (SEM) images of extruded actions of packing bed for two capillary columns of different diameters, al 750 (bottom image) and b) 30-μm-i.d. 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.³
