2020-10-08 22:53:25 +0000 UTCThe solvent polarity has a substantial effect on the equilibrium between the two chair forms of trans-1,2-difluorocyclohexane. The following table quantifies the effect on solvent polarity on this equilibrium. Draw the chair form of each conformer with the axial-axial as reactant and equatorial-equatorial as product. Use Spartan (PM3) to calculate the dipole moment (this will be listed under “Display/properties”) for each. Explain why the eq-eq conformer is favored by solvents with a higher dielectric constant (e). J. Org. Chem. 2005, 70, 8381-8384. (Note: the solvent dielectric constant is proportional to its polarity) Compound E 13C data 22.59, 23.57, 52.66, 202.71 d Broadband decoupled DEPT-90 DEPT-135 (positive peaks) DEPT-135 (negative peaks) Solvent Methylcyclohexane di-n-butylether Tetrahydrofuran Acetone e K=eq/ax 2.0 4.4 3.1 7.6 7.6 29.8 20.7 51.3
