Exam 20: Amines

What is the principal product when aniline is treated with sodium nitrite and hydrochloric acid at 0-5 $\degree$ C and this mixture is added to p-ethylphenol?

What final product is expected from the following reaction sequence?

The best synthesis of 3,5-dibromotoluene would be:

Before modern spectroscopic methods were developed,structures of many complex amines were elucidated by examining the products obtained during Hofmann elimination of their quaternary ammonium hydroxides.The typical procedure involved the following steps,repeated as necessary,depending on whether the amine was primary,secondary or tertiary,until the final product was nitrogen-free: i)CH₃I (excess);ii)Ag₂O,H₂O;iii)heat.What product(s)is (are)likely to be formed if 3,4-dimethylpiperidine is subjected to the above procedure?

What would be the product of the following reaction?

Eliminations that follow the Hofmann Rule tend to give the ______________ alkene as the major product.
