Question
Chapter 13, Problem 43E
Interpretation Introduction
Interpretation:
The molecules that are nonpolar with polar bonds are to be predicted.
Concept introduction:
The Lewis structure shows the connectivity between atoms by identifying the lone pairs of electrons in a compound. Lewis structures are also known as Lewis dot structures. The valence electrons around an atom are shown by dots. Bonds between atoms are shown by lines and the lone pair of electrons is shown by a pair of dots.

32. What impact (increase, decrease, or no change) does each of the following conditions have on the individual
components of the van Deemter equation and consequently, band broadening?
Increase temperature
Longer column

34. Figure 3 shows Van Deemter plots for a solute molecule using different column inner diameters (i.d.).
A) Predict whether decreasing the column inner diameters increase or decrease bandwidth.
B) Predict which van Deemter equation coefficient (A, B, or C) has the greatest effect on increasing or
decreasing bandwidth as a function of i.d. and justify your answer.
Figure 3 Van Deemter plots for hydroquinone using different column inner diameters (i.d. in μm). The data was
obtained from liquid chromatography experiments using fused-silica capillary columns packed with 1.0-μm particles.

elow are
experimentally determined van Deemter plots of column efficiency, H, vs. flow rate. H is a
quantitative measurement of band broadening. The left plot is for a liquid chromatography application and the
night is for gas chromatography. Compare and contrast these two plots in terms of the three band broadening
mechanisms presented in this activity. How are they similar? How do they differ? Justify your answers.?
