(a) Interpretation: How the given transformation can be carried out is to be shown. Concept introduction: An alkene can be transformed into its constitutional isomer through a series of reactions. This generally involves the electrophilic addition, of a Bronsted acid such as HBr to the alkene followed by an elimination of HBr. Another possibility is the addition of a weak acid like H 2 O in the presence of a strong acid. The choice of the electrophilic addition reaction and the choice of the second stage elimination reaction depends on the nature of the starting alkene and the desired product, particularly the type of carbocation that will form during addition as well as during the second stage elimination. If the formation and rearrangement of a carbocation are needed for shifting the position of the double bond, the elimination must be an E1 reaction.

PLEASE READ!!! I DONT WANT EXAMPLES, I DONT WANT WORDS OR PARAGRAPHS FOR THE MECHANISM!!! THANKS First image: QUESTION 6. I have to show, with ARROWS and STRUCTURES, the mechanism of the reaction at the bottom. Also I have to show by mecanism why the reaction wouldn't work if the alcohol was primary. I also tried to draw the mechanism, tell me what to change. Please note that its an AMIDE thats formed not an AMINE the nitrogen has ONE hydrogen and one Phenyl-C-Phenyl. I already asked for this mechanism and got as a final product ...-NH2 not whats shown on the picture, thank you Ths second part. QUESTION 3. I just need a way to synthesize the lactone A, I already started please continue from where I left it Second image: I simply need the products, substrates or reagents, thank you
