WebAn interesting fact about the cycloalkanes is that they have different relative stabilities, and the stability depends on the size of the ring. It has been observed that cyclic compounds found in nature are usually in 5- or 6-membered rings, and 3- or 4-membered rings are rare. Web14 de feb. de 2024 · Conformations of cyclohexane. Cyclohexane which is the most common cyclic structure found in nature exists primarily in a chair conformation in which all bonds are 111 o that is very close to tetrahedral value 109.5 o and all six pairs of \(\ce{H's}\) are staggered as shown in Figure \(\PageIndex{7}\).
