Which of the following is not true about the five membered rings? Correct Answer Five membered rings are more stable than 6 membered rings

6-membered rings can have 3D conformations, such as the chair conformation (the more stable) and the boat conformation. These conformations relax the angles, getting them closer to the tetrahedral angle. Thus, cycle gains stability. That is why 5-membered rings are less stable than 6-membered.

The popular notion that a tree's age can be determined by counting number of internal rings in its trunk is generally true. Howeevr, to help regulate the internal temperature of the tree, the outermost layers of wood of the Brazilian ash often →peel away when the temperature exceeds 95 degrees Fahrenheit, leaving the tree with fewer rings than it would otherwise have. So only if the temperature in the Brazilian ash's environment never exceeds 95 degrees Fahrenheit →elav eing the tree with fewer rings than it would otherwise have.
