The mechanism for the given reaction is to be completed by adding curved arrows to show the movement of electrons. Concept introduction: Transesterification reaction is the one in which one ester is converted to another. A typical reaction involves a nucleophile and a carboxylic acid derivative. It is called a nucleophilic addition–elimination mechanism, which describes the two steps that take place. Step 1 is a nucleophilic addition in which a nucleophile attacks the electron poor carbonyl carbon. This forces the pair of electrons from the initial C=O to oxygen atom, which generates a negative charge in it. The product of that step is a tetrahedral intermediate, which, in Step 2, undergoes nucleophile elimination. A lone pair of electrons on the negatively charged O atom is used to regenerate the C=O double bond, and the leaving group departs as methoxide ion.

Answer 1

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.

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
