WebJul 19, 2024 · in cyclohexane, the C−C−C angle is very close to the tetrahedral angle. all the carbon-hydrogen bonds are staggered. the ring strain is independent of the number of CH2 groups. bond angles are not optimal in the cyclohexane ring. the carbon-hydrogen bonds in cyclohexane are always eclipsed. there are no eclipsed bonds in cyclohexane. WebFor this class, we will always find that the most stable conformation is staggered (i.e., 1, 3 or 5), and the least stable is eclipsed (i.e., 2, 4 or 6).). Comparing 1, 3 and 5, we see that 1 has two “bad” gauche interactions, …

Web1,3-diaxial strain is another form of strain similar to syn-pentane. In this case, the strain occurs due to steric interactions between a substituent of a cyclohexane ring ('α') and gauche interactions between the alpha substituent and both methylene carbons two bonds away from the substituent in question (hence, 1,3-diaxial interactions).
