1. Assign the peak values for the characteristic functional group bonds (C-Br, C-N, N=O, and aromatic C-C) from the IR spectra of your product. 2. Assign the characteristic protons from the 'H NMR spectra of your product. The 'H NMR spectra is (1) for pure ortho-product or (2) for pure para-product. If mixture, then what is the major product and what is the minor product? Provide your answer with chemical structures. 3. In 2-bromonitrobenzene and 4-bromonitrobenzene, which compound is more polar and why? 4. In 2-bromonitrobenzene and 4-bromonitrobenzene, which compound has higher MP and why? 5. In 2-bromonitrobenzene and 4-bromonitrobenzene, which compound has a lower R value on a silica (polar) TLC plate and why? 6. The ratio of two isomers is usually found to be 1:3 (2-bromonitrobenzene (minor):4-bro- monitrobenzene (major)). Use this ratio and the amount of 4-bromonitrobenzene actually isolated in your experiment to estimate the experimental yield of mononitration of this reaction
