Chapter 4, Problem 4.36P
Interpretation Introduction

Interpretation:

The ring strain per CH2 group and the total ring strain of cyclononane is to be calculated. Which compound has more ring strain, cyclononane or cycloheptane, is to be stated.

Concept introduction:

Ring strain is the type of instability that exists when bonds in a molecule form angles that are abnormal. Ring strain can also be defined as the increase in energy due to geometric constraints on the ring. For a given cycloalkane, the ring strains per CH2 group can be calculated using heats of combustion values. Heat of combustion (ΔH0) is the energy given off in the form of heat during a combustion reaction. Any difference in the heat of combustion per CH2 group for two cyclic alkanes reflects a difference in ring strain per CH2 group. The total ring strain is obtained by multiplying the strain per CH2 group by the number of CH2 groups, (n). For cyclohexane, the ring strain per CH2 group and the total ring strain is 0 kJ/mol, hence it is used as a standard to compare the ring strains and the total ring strain for other cycloalkanes.

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?
