Combine evidence from percentage composition, degree of unsaturation, mass spectrometry, IR and 1H NMR spectra to determine the structure of an unknown organic compound, justifying each deduction from the data.
In the mass spectrum of Y, the molecular ion peak appears at m/z 88. (i) Y contains no multiple carbon–carbon bonds and no rings. Deduce its molecular formula. Use section 7 of the data booklet. Shown below is the high-resolution NMR spectrum of Y,…
The IR spectrum of HA is shown. Two absorption bands are labelled: Y is a very broad band centred near and Z is a band of medium intensity near . (i) Using section 20 of the data booklet, identify the functional…
