(a)
Interpretation:
Both the chair conformations for cis-1,2-dimethylcyclohexane is to be drawn and the compounds (compared with other given compounds) having equal numbers of axial and equatorial substituents are to be determined.
Concept Introduction:
The isomers are drawn on the basis of cis and trans-positions of the given compound, also in certain conformations, C-H bonds exist in two forms: vertical with the ring (axial) and peripheral with the ring (equatorial).
(b)
Interpretation:Both the chair conformations for trans-1,2-dimethylcyclohexane is to be drawn and should identify the compounds (compared with other given compounds) having equal numbers of axial and equatorial substituents.
Concept Introduction:The isomers are drawn on the basis of cis and trans-positions of the given compound, also in certain conformations, C-H bonds exist in two forms: vertical with the ring (axial) and peripheral with the ring (equatorial).
(c)
Interpretation:Both the chair conformations for cis-1,3-dimethylcyclohexane are to be drawn and the compounds (compared with other given compounds) having equal numbers of axial and equatorial substituents are to be determined.
