Please answer the following questions. Draw the synthesizing of the compounds.
1. Starting with toluene, prepare 2-bromo-4-nitrotoluene.
2. Starting with toluene, prepare 2,4,6-trinitrobenzoic acid.
3. Starting from benzene, prepare p=chlorostyrene.
4. p-Bromotoluene reacts with potassium amide to give a mixture of m- and p- methyl aniline. Explain how these products are produced by showing the mechanism involved. (draw).
This solution provides detailed drawings of synthesizing compounds.
