Questions about Organic Chemistry

[Dc Nilbog]

Hi again,

 

I am writing a Chemistry report once again and I need some assistance from you. I am having trouble on answering some of the questions.

 

Questions:

1) Why is acetylation of the amine group useful in organic synthesis?
2) Explain why the amine group and its acetylated derivative are ortho/para directors.
3) Aniline cannot be nitrated directly with the usual nitrating mixture of the nitric acid/sulphuric acid because considerable charring takes place. Write equations to show how you might prepare p-nitroaniline from aniline.

 

I have searched around 'Google' but couldn't find anything.

 

Thanks for your help.
