For cis-1,3-dimethylcyclohexane, which structures represent the possible boat conformations?
Homework Answers
Cyclohexane can exist in three stable conformations. They are chair, boat and twist boat. Among the three conformations, chair conformation is most stable. In boat conformation of cyclohexane, two types of groups are present at each carbon atom. They are axial groups and equatorial groups. We should identify the cis conformations from the given boat conformations.
If two substituents are cis to each other then they are in up, up (or) down, down to each other in boat conformation.
If two substituents are trans to each other then they are in up, down (or) down, up to each other in boat conformation.
The given boat conformations are,
The possible boat conformations for the given cis-1,3-dimethylcyclohexane are,
Thus, the possible boat conformations of cis-1,3-dimethylcyclohexane are,
