Question

Putting It Together: Spectroscopy 1. You identity a new compound X Mass spectroscopy suggests a molecular forma following IR and proton NMR spectra are recorded: troscopy suggests a molecular formula of CH120, and the Wavelength (m) 0.05 Absorbance 80.40 0.60 204 4000 3500 3000 2500 100 500 400 200 2000 1800 1600 1400 1200 1000 Frequency (cm ) 200 500 TAHT 31 2H 1 H 6.0 5.0 4.0 8 (ppm) Deduce the structure of compound X, and explain the assignment of all of the important features in both spectra above. (Hint: What information can you deduce from the molecular formula alone?)
