Propose a mechanism(s) for the reactions leading to these products and used curved arrows to show the movement of electrons.Tunicates are marine animals that are called "sea squirts" because when they are taken out of water, they tend to contract and expel seawater. Lepadiformine is a cytotoxic agent (toxic to cells) isolated from a marine tunicate. During a recent synthesis of lepadiformine, the investigators observed the formation of an interesting by-product (3) while treating diol 1 with a reagent similar in function to PBr3 (J. Org. Chem. 2012, 77, 3390–3400):dedcue the major organic product from the following reations. be ablw to draw hydration halogenation hydrohalogenation, halohydrin formation, oxymercuratiom demercuration qnd hydroboration oxidation.

- Oxidation of cholesterol converts the alcohol to a ketone. Under acidic or basic oxidationconditions, the C“C double bond migrates to the more stable, conjugated position. BeforeIR and NMR spectroscopy, chemists watched the UV spectrum of the reaction mixture tofollow the oxidation. Describe how the UV spectrum of the conjugated product, cholest-4-en-3-one, differs from that of cholesterol2-butanol + NOx + hv (assume the carbon-hydrogen bond on the carbon adjacent to the carbonwith the alcohol group is the weakest) For each mechanism, provide the photolytic cycle, a source for hydroxyl radical (if needed) AND atermination step. You may stop when you have accounted for all radicals AND all VOCs are stable (i.e., ifformaldehyde is a product of your mechanism, you do not have to oxidize that molecule to).6. Identify the best reagent(s) for this reaction. (see attached screenshot). a. H2SO4, HgSO4, H2O b. 1. Disiamylborane, 2. HO–, H2O2 c. K2Cr2O7, H+ d. NaOCl e. H2, Pd
