Nitration; THIS PROBLEM IS FOR OTA 104318

Upon nitration, 1-naphthol (1-hydroxynaphthalene) yields 2,4-dinitronaphthol, while 1-nitronaphthalene yields, 1,8-dinitronaphthalene and 1,5-dinitronaphthalene. How do you account for this contrast

Pyrrole; THIS PROBLEM IS FOR OTA 104318 ONLY

1)Show that pyrrole is aromatic. 2)Account for it's aromaticity on the basis of orbital theory.

Multiple Spectra/Indentifying Structures from spectra

Please identify the structure giving the following spectra (NMW, IR, Mass Spec, etc...) and state how you arrived at your structure (give reasons such as peak identifcation and mass, etc.....)I need a minimum of 4 reasons and/or examples.. Thank you very much. This is needed as soon as possible

Color change when benzoin is oxidized to benzil

What structural features make benzil yellow and benzoin white? How and why does the color change occur when benzoin is oxidized to benzil? The reaction uses a solution of ammonium nitrate in the presence of a catalytic ammount of copper (II) acetate to oxidize benzoin.
