WebThe twist-boat conformation of a cyclohexane also tends to be lower in energy and thus more stable than the extreme boat conformation because the eclipsed hydrogens or substituents of the extreme boat conformation … WebJun 28, 2015 · A cyclohexane boat is like boat — it has a bow, a stern and two sides. This is how you draw a boat. Step 1. Draw two horizontal parallel lines. These will form the … WebCyclohexaneis a good example of a carbocyclic system that virtually eliminates eclipsing and angle strain by adopting non-planar conformations, such as those shown below. 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). robert wouters
