A chemist allows some pure (2S,3R)-3-bromo-2,3-diphenylpentane to react with a solution of sodium ethoxide(NaOCH2CH3) in ethanol. The products are two alkenes: A (cis-trans mixture) and B, a single pure isomer. Under thesame conditions, the reaction of (2S,3S)-3-bromo-2,3-diphenylpentane gives two alkenes, A (cis-trans mixture) and C.Upon catalytic hydrogenation, all three of these alkenes (A, B, and C) give 2,3-diphenylpentane. Determine the structuresof A, B, and C; give equations for their formation; and explain the stereospecificity of these reactions
1,4-Pentadiene (CH2=CH-CH2-CH=CH2) is a liquid at room temperature and has a density of 0.66 g/mL and molar mass of 68.12 g/mol. In a laboratory experiment, 3.80 mL of this compound was treated with 4.80 mL of conc. H2SO4 (100% w/w; molar mass 98.08 g/mol). Note that the density of conc. H2SO4 is 1.84 g/mL. The resulting sulfate ester was then treated with 1.20 mL of water (molar mass 18.02 g/mol) affording, after work- up, 2,4-pentanediol (molar mass 104.15 g/mol) as the crude product. The crude product was then purified by simple distillation, which yielded 2.00 g of pure product. What is the theoretical yield of 2,4-pentanediol expressed in grams? Show calculations. What is the percentage yield of pure 2,4-pentanediol?

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):
