(a)
Interpretation:
The axial and equatorial chair conformation of given compounds are drawn and the lowest energy conformation should be determined.
Concept Introduction:
Conformational isomers:
- The two or more compounds have same molecular formula and different structural formulas from the result of C-C single bond rotations are called conformational isomers.
- The chair conformation of Cyclohexane have two positions of substituents which are axial and equatorial.
- The normal wedge representations are used to draw the positions of Cyclohexane conformations. The dark wedge bond represents the group is pointing above the plane and the light wedge bond represents the group is pointing below the plane.
- The atom or group is occupy at similar to a vertical axis passing through the chair conformation of Cyclohexane ring is called axial position.
- The atom or group is occupy at similar to horizontal axis passing through the chair conformation of ring is called equatorial position.
- The substituents are occupy in equatorial position is more stable than axial because of the 1,3-diaxial interactions are less in equatorial position.
