Cis and trans chair conformations

WebCyclohexane contains a six-membered saturated cyclic ring that experiences severe angular strain in the corresponding planar form. Hence, cyclohexane exists in chair conformations where the angular strain becomes nil. There are two available positions for the substituents in the chair conformation, i.e., equatorial and axial. WebThe main distinction between cis and trans cyclohexane is that the substituents in cis cyclohexane point in the same ring plane, whereas the substituents in trans cyclohexane …
