(d) Predict the multiplicity observed for H1 in the ¹H NMR spectrum of 4ax and 4eq. Ignore couplings to the OH proton and long-range couplings (more than 3 bonds). Assume the following 3- bond coupling constants between two axial protons Jax-ax, two equatorial protons Jea-eq, and one axial and one equatorial proton Jax-eq: Jax-ax = 10Hz Jeg eq = 4Hz Jax-eq = 3Hz 4ax: multiplicity of H1 = 4eq: multiplicity of H1 =_ (e) Use the coupling constants specified in part (d) and assume that 4ax and 4eq are formed in a 1:1 ratio. Sketch the multiplets that would be observed for H1 in both isomers according to scale: One multiplet in each box. Represent individual peaks in each multiplet with vertical lines. The height of each line should be proportional to the intensity of the peak in the multiplet. 2 Hz 2 HE #1 4eq 4ax H₂ OH OH CI
