Question

Quizplus · Accepted Answer

The least stable conformation for 1-tert-butyl-3-methylcyclohexane is when both the tert-butyl and methyl groups are in the axial positions (B). This configuration creates the most steric hindrance and destabilizes the molecule due to increased 1,3-diaxial interactions.
