Highest energy conformation of cyclohexane
Webdraw a boat (Figure 3) and 2) knowing that, if possible, the lowest energy boat conformation, just like chair conformations, should have groups with large A values situated at the equatorial positions. The method is shown for ( 1) (Figure 5). It is as follows: 1. Convert a planar cyclohexane structure into the lowest energy chair conformation. 2. http://research.cm.utexas.edu/nbauld/teach/cyclohex.html

WebScore: 4.9/5 (31 votes) . While there are an infinite number of conformations about any sigma bond, in ethane two particular conformers are noteworthy and have special names. In the eclipsed conformation, the C-H bonds on the front and back carbons are aligned with each other with dihedral angles of 0 degrees.
