12.6: The Larger Cycloalkanes and their Conformations

WebJun 21, 2024 · Cyclohexane is a good example of a carbocyclic system that virtually eliminates eclipsing and angle strain by adopting non-planar conformations. Cycloheptane and cyclooctane have greater strain than cyclohexane, in large part due to transannular crowding (steric hindrance by groups on opposite sides of the ring). WebApr 23, 2005 · For the 5/7 ring system the difference in steric energy between diastereomer with l,l and l,u configuration amounts to 1.85 kcal/mol whereas for the 5/8 system the corresponding difference was 2.65 kcal/mol. The calculation suggest cyclization of the l,l substrates to 5/7 ring system involves somewhat lower strain. It should be noted that ...

WebSep 24, 2024 · Cyclopentane has very little angle strain (the angles of a pentagon are 108º), but its eclipsing strain would be large (about 40 kJ/mol) if it remained planar. Consequently, the five-membered ring adopts non-planar puckered conformations whenever possible. Rings larger than cyclopentane would have angle strain if they were planar. WebAug 27, 2024 · Ring Strain. Table 4.3.1 lists the heat of combustion data for some simple cycloalkanes. These cycloalkanes do not have the same molecular formula, so the heat of combustion per each CH 2 unit present in each molecule is calculated (the fourth column) to provide a useful comparison. From the data, cyclopropane and cyclobutane have …

WebJul 14, 2024 · Cycloheptane is therefore not strain-free and experiences pseudorotation [10,11,12]. Unlike small rings, medium-sized rings have less angle and torsional strain, but they exhibit a high level of steric strain. This is often due to the unfavourable transannular interactions involving the hydrogen atoms pointing inside the ring. ... Higher energy ...
