JCH3,CH = 6.1 Hz

Please check here if you came up with a different answer!

The CH-protons of the same molecule (CH3)3CH-O-CH(CH3)2 give rise to a signal at d = 3.56 ppm.
  1. What is the multiplicity of this signal?
  2. How large is the coupling constant JCH,CH3?
  3. List the relative intensities of the individual lines and make a table with the distance of the individual lines from the line at the center of the multiplet (3.56 ppm) on the Dn and the Dd scale. The proton frequency n0 of the spectrometer used is 60 MHz.
  4. Draw the expected multiplet using the x-axis below !
