I have several questions that I am doing for extra practice that I do not understand. Your help is greatly appreciated:
1) Write reactions showing how nylon can be synthesized to react with (a) basic dyes and (b) acidic dyes.
2) Write the resonance form of dimethylaniline most prone to react with diazotized sulfanilic acid.
3) Write the resonance form of indigo present in base.
4) Write the mechanism for the formation of t-butyl-2,5-dimethoxy benzene.
Thanks for any help, I am having lots of trouble with these questions.
