The conformation with two consecutive atoms out of the plane, one above and one below, is called <scene name='90/900784/Cyclopentane/4'>twist</scene>. More than two atoms are never out of plane because the remaining three atoms always define a plane. | The conformation with two consecutive atoms out of the plane, one above and one below, is called <scene name='90/900784/Cyclopentane/4'>twist</scene>. In the example, carbon 4 and 5 are out of plane. Again, you can define a plane using the five possible sets of three consecutive atoms (buttons above). As you will discover, the 4/5 twist is very close in conformation to the carbon 4 envelope and the carbon 5 envelope. | ||
