3. The following IR spectra are of two different compounds both with the molecular formula of Hofmistake) Identify the two compounds and interpret the significant signals in the IR spectra. 1731
molecular formula is not given No forma For the IR spectrum, each major signal should be identified by wavenumber (stretching. frequency) and assigned to the corresponding bond. A conclusion about functional groups should also be drawn from the spectrum. In the C-NMR spectrum, the chemical shift of each signal should be noted and a structural assignment should be made. In 'H-NMR spectrum, the chemical shift, integration, and splitting pattern for each signal should be noted and a structural assignment should...
