1. Write a chemical reaction in which the iodide ion replaces the diazonium group in a diazonium salt.
2. pKb for aniline is more than that for methylamine. Why?
3. Methylamine solution in water reacts with ferric chloride solution to give a precipitate of ferric hydroxide. Why?
4. Aniline does not undergo Friedel-Crafts reaction. Why?
