Boat or chair conformation more stable
WebThe least stable conformation of 1-methyl-4-chlorocyclohexane is the one where the methyl group and the chlorine atom are in the same axial position, and the molecule adopts a twist-boat conformation. Most stable. The most stable conformation is the chair conformation, where all carbons are in the same plane and have a tetrahedral geometry.
