Quizplus · Accepted Answer

This is true. Cyclopentane rings can adopt a variety of conformations, including chair, boat, twist-boat, and envelope conformations. The envelope conformation can have the C-1 or C-5 atom pushed out of the plane of the ring, resulting in four possible conformations for each atom. Therefore, there are a total of 10 possible envelope conformations for cyclopentane rings.
