sulfanilic acid to methyl orange

Hello, Could someone help me convert sulfanilic acid to the dye methy orange? I need to use another organic compound to assist. Thanks

deactivators

Hello, I am having some trouble explaining why the attached molcule is an otho-para director although a weak deactivator. I believe it is because of resonance forms, but that is as far as I have gotten. Thanks, Heath

Crystal Formation; Mechanism/Reaction Formula: sn2 reaction - 1-bromobutane, diethyl ether and piperidine

1cm3 of diethyl ether and 1cm3 of 1-bromobutane are mixed in a test tube. Five drops of an amine, piperidine, are added to the tube. The tube is then heated until precipitate/crystals are formed. The crystals are taken out of the test tube. 1) What do the crystals consist of? 2) Write a mechanism/reaction formula for the rea ...continues
