Question

The stable conformers(s) of trans-1, 4-dimethyl cyclohexane is/are:

• A. 1-axial-4-equatorial form
• B. 1-axial-4-axial form
• C. 1-equatorial-4-axial form
• D. 1-equatorial-4-equatorial form

Answer 1

The correct option is D 1-equatorial-4-equatorial form

The stable conformers of trans-1,4-dimethyl cyclohexane is 1-equatorial-4-equatorial form.
1,4-diequatorial conformation is most stable as the steric interactions are minimum.
1,4-diaxial conformation is least stable as the steric interactions are maximum.
