- 3. Label nonequivalent hydrogens in the structures below with numbers (1, 2, 3, etc.)The following molecule, the silicon analog of formaldehyde, has never been successfully prepared. H2SiO or H2Si=O The following reaction was attempted by researchers in order to synthesize this unusual compound: H2Si=S + P4O10 → H2Si=O + P4O9S None of the desired compound (H2Si=O) was obtained. Instead, the following molecule was obtained: (H2SiO)2 a molecule in which the O and Si form an …Si-O-Si-O… square. Further research indicated that although H2Si=O formed, it immediately formed (H2SiO)2 and released a substantial amount of energy according to the reaction: 2 H2Si=O → (H2SiO)2 + heat Based on the information above and your knowledge, what can be concluded about the relative strength of the Si-O and Si=O bonds? Question 24 options: A) An Si=O bond is stronger than two Si-O bonds. B) An Si=O bond is weaker than two Si-O bonds. C) An Si-O bond has the same strength as an Si=O.…I put in the answer for compound A, (dimethyl‐lambda4‐sulfanylidene)cyclopropane, and the product 9‐oxadispiro[2.0.44.13]nonane, in the boxes, but it says it's incorrect.

- 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.
