(iii) A compound of unknown structure was found to have a molecular formula CHNO. The wavenumber () of selected bands from the IR spectrum of the compound are given below: v (cm)-2980-2830 (multiple overlapping bands, medium intensity), 2250 (medium), 1125 (strong) The 'H NMR spectrum (400 MHz, CDCls solvent) of the compound is shown, with the integration of the signals indicated by the curves. The chemical shifts (8) and coupling constants of the iH NMR signals are: 83.50 (tJ-7 Hz),...
