Pyridine do not give good yield when undergoes electrophilic aromatic substitution, whereas pyridine N-oxide undergoes electrophilic aromatic substitution to give moderate yield is to be stated. Concept introduction: The electrophilic aromatic substitution reaction involves addition of electrophile (electron deficient species) on aromatic ring. These reactions occur in the presence of Lewis acid catalysts like AlCl 3 . To determine: Pyridine do not give good yield when undergoes electrophilic aromatic substitution, whereas pyridine N-oxide undergoes electrophilic aromatic substitution to give moderate yield.

(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
