Cyclohexane is more stable in its chair conformation. In chair conformation of cyclohexane, two types of groups are present at each carbon atom. They are axial groups and equatorial groups.
In chair conformation, six axial positions and six equatorial positions are present. In chair conformation, vertical bonds are taken as axial and slanted bonds are taken as equatorial.
Part a
Chair conformation of cyclohexane with axial and equatorial positions is,
Part b
The structure of cyclohexane with axial and equatorial groups is as follows:
Ans: Part aThus, the frame work of cyclohexane in a chair conformation is,
Part bThus, the positions that are gauche to the Y are,
(a) Given a cyclohexane framework in a chair conformation, label each position as axial (ax.) or...
The cyclohexane derivative shown exists primarily in the more stable of the two available chair conformations. Give the position, axial or equatorial, of each of the three groups shown in the more stable chair conformation. If a group divides its time equally between axial and equatorial positions, indicate this with ax/eq The table of "Axial Strain Energies for Monosubstituted Cyclohexanes" found in the "Strain Energy Increments" section of the Reference tool is useful for answering this question. CH-CH2 CI Group...
