Question
Chapter 7, Problem 21CTQ
Interpretation Introduction
Interpretation: From the given set of molecules, the one with lower potential energy needs to be determined.
Concept Introduction: The molecule with lowest potential energy is most stable. In the chair conformation of the cyclohexane, the stable conformation is when large groups are present in the equatorial positions. The equatorial positions in the chair conformation points away from the ring thus, there is less steric hinderance.

When an unknown amine reacts with an unknown acid chloride, an amide with a molecular mass of 163 g/mol (M* = 163 m/z)
is formed. In the infrared spectrum, important absorptions appear at 1661, 750 and 690 cm. The 13C NMR and DEPT spectra
are provided. Draw the structure of the product as the resonance contributor lacking any formal charges.
