Chapter 19.2, Problem 8E

Which compounds can coupling reaction occur best with arendiazonium salts? Why is that?

Match the reagents, materials and parameters to its appropriate description.

You were told that is best to use a methyl halide or a primary alkyl halide for the reaction of an acetylide ion with an alkyl halide. Explain why this is so.

When these two compounds are subjected to iodination like how vanillin is subjected to iodination, predict the products that could be formed. Need help please.

What is the Noyori asymmetric reduction?

Outline the mechanism showing both products formed for the reaction of ammonia (2 mole equivalent) with 1-bromobutane (1 mole equivalent).

Draw all the resonance forms of the sigma complex for nitration of bromobenzene at the ortho, meta, and para positions. Point out why the intermediate for meta substitution is less stable than the other two.

Q2 Explain why copper iodide increases the reactivity of organolithium compounds towards alkyl halides.

During the transfer hydrogenation of dehydrozingerone to zingerone ideally the yellow color fades from the solution. Explain why this is so. Be sure to include chemical structures.
