I'm not sure how to draw the mechanism and where to connect them correctly , can someone explain **Transcription for Educational Website:**---**Question 3:**Deduce the structure of each boxed intermediate and products in the following reaction sequence with detailed arrow-pushing.**Reaction Sequence:**- Reactants: A benzyl phosphonium ylide (illustrated as a formula with a triphenylphosphine group) is shown reacting with a ketone (featuring a double-bonded oxygen and two phenyl groups). - Notable points in the diagram: - The phosphonium ylide has a positive charge on phosphorus. - The ketone has oxygen with a lone pair.- Reaction Arrow: Indicates the process proceeds to form intermediates and products.- The first arrow points towards a proposed intermediate structure featuring a pentacyclic ring system with an attached triphenylphosphine oxide group.**Observations and Queries:**- The diagram includes handwritten notes: - "Betain?" indicated under the intermediate structure. - Final Product boxed and labeled as "Oxophosphonate".**Diagram:**- The reaction mechanism is detailed with structures indicating movement via curved arrows, highlighting electron transfer and intermediate formations.- The charted reaction showcases typical features of a Wittig or related reaction path, focusing on transformation to a potential betaine intermediate and culminating in an oxophosphonate product.--- This transcription presents the details with the assumption that readers have foundational knowledge in organic chemistry, specifically reaction mechanisms involving ylides and organophosphorus compounds.

The above reaction is Wittig reaction, in which a carbonyl compound transforms into an alkene compound. Reagents:- carbonyl compound, phosphonium ylide and alkyl halide. Reaction:- Ketone in presence of phosphonium ylide forms an alkene. In spite of having higher bond energy of carbonyl than alkene, the dissociation occurs due to the formation of stable triphenyl phosphine oxide. Reaction:- The reaction mechanism is shown below,
