Explain the following statement: "Compared to methylcyclohexane, tert-butylcyclohexane has a higher percentage of molecules with its substituent in an equatorial position."

• A. The methyl group is bulkier and experiences greater 1,3-diaxial interactions, making the equatorial conformer less table.
• B. The methyl group is smaller and experiences greater 1,3-diaxial interactions, making the equatorial conformer less table.
• C. The tert-butyl group is larger and experiences greater 1,3-diaxial interactions, favoring the equatorial conformer.
• D. The tert-butyl group is smaller and experiences greater 1,3-diaxial interactions, favoring the equatorial conformer.

Answer: (C)
