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...
