In chemistry, conformational isomerism is a form of stereoisomerism in which the isomers can be interconverted just by rotations about formally single bonds (refer to figure on single bond rotation).. And the reason why it's useful to know that name is when we talk about the different configurations, the different chair and boats, whether something is equatorial or axial can change if this were to flip up, or vice versa, and things like that.. This video focuses on how to identify if a particular chair conformation is cis or trans..
Chair and boat shapes for cyclohexane. created by sal khan. constitutional isomers and meso compounds | khan academy - duration: 13:36. khan cyclohexane ring flip and boat conformation. Example 2: cyclohexane : chair (left) and boat (right).these two forms can be interconverted by twisting the ring structure. configurational isomers are stereoisomers that do not readily interconvert at room temperature and can (in principle at least) be separated.. This is the so- called "twist boat" conformation. however, since this conformation is 5.5 kcal/mol higher in energy than the chair conformation, it is not a highly populated state.again, most of the strain energy results from bonds which are eclipsed or partially eclipsed, i.e., from torsional strain..
