Web- [Voiceover] Here we have a model of the cyclohexane molecule and it looks like it's a flat hexagon from this perspective, but it isn't really. If we turn it to the side we can see this is not a planar molecule. This is called the chair conformation of cyclohexane. WebStep 1: Cis and trans isomers The stereoisomers in which both functional groups are present on the same side of the plane are called cis isomers. The stereoisomers in which both functional groups are present on the opposite side of the plane are trans-isomers. Step 2: Identification of cis and trans isomers from the given chair structures

WebOnly $35.99/year. Arrange the four conformations of cyclohexane in order from lowest energy to highest energy. The chair, with all bonds staggered and no torsional strain, is the lowest-energy conformation of cyclohexane.
