The cyclohexane ring is essentially free of ring strain because Check all that apply. there are neither eclipsed nor gauche interactions in cyclohexane. cyclohexane adopts the fully staggered conformation. in cyclohexane, the C-C-C angle is identical to the tetrahedral angle. the carbon-hydrogen bonds in cyclohexane are always eclipsed. the ring strain is independent of the number of CH2 groups. the values of estimated and experimental heat of the combustion for cyclohexane are the same. here is maximum torsional strain in the cyclohexane ring. Cyclohexane exists in different types of conformations. The most stable among the conformers are the chair and boat conformations. The bond angles are approximately 109.5 degree in both the chair and boat forms of cyclohexane. In the figure below, and are the chair conformers whereas is the boat conformer. The conformations keep flipping; that is, the conformations undergo interconversions, as shown in the figure below. In the conversion of the conformations of cyclohexane shown below, which of the following statements are true? In the conversion from I to II, the dihedral angle between the hydrogen atoms on adjacent carbon atoms goes on increasing. In the conversion from I to III, the bond angle between the C-C-C bond of cyclohexane remains 109.5 degree . In the conversion from I to II, steric strain is not introduced. In the conversion from I to II, at Cl and C4, C-H bonds are brought closer together, increasing repulsive interactions between them. In the conversion from I to II, C-H bonds on C2, C3, C5, and C6 become neither axial nor equatorial. the conversion from I to III, all axial bonds become equatorial, and all equatorial bonds become axial. Identify cis and trans isomers from the following isomers of 1,2- and 1,3-dimethylcyclohexane in their chair conformations. Drag the appropriate isomers to their respective bins.
