Explanation:

Calculating angle strain in actual compounds

•

So far we only have a predicted value of angle strain in planar rings. We need a measure of angle strain in actual compounds, so that we can compare this to the predicted values.

•

The preferred angle in actual compounds can be determined, for an n-membered carbocyclic ring, by taking the average internal angle across a large number crystal structures. Angle strain can then be calculated as the difference between this average internal angle and the ideal sp3 angle of 109.5.

•

Calculate, from crystal structure data, the actual angle strain in cyclohexane. For this task you are provided with 5 structures each containing a cyclohexane ring (CSD refcodes: ALIPIU, AZANUK, CYCHEX, CHXDCA and BCYHAC). To view a structure click on its refcode in the Structure Navigator on the right hand side of the main Mercury window. For each structure measure all six internal C-C-C angles, then calculate the average internal angle of each structure and the overall average across the whole set.
